Subject: [PATCH 01/16] Improve guest handling in comments

1. No contacts menu for guests (can't use it anyway)
2. No contacts menu on guests (no data available)
3. Show "You" as author name above "new" box
4. Do not try to load avatars of guests (results in 404)

+# jsHashes [![Build Status](https://travis-ci.org/h2non/jshashes.svg)](https://travis-ci.org/h2non/jshashes) [![NPM version](https://img.shields.io/npm/v/jshashes.svg)](https://www.npmjs.com/package/jshashes) 
+
+`jshashes` is lightweight library implementing the most extended [cryptographic hash function](http://en.wikipedia.org/wiki/Cryptographic_hash_function) algorithms in pure JavaScript (ES5 compliant).
+
+The goal is to provide an dependency-free, fast and reliable solution for hash algorithms for both client-side and server-side JavaScript environments. 
+The code is fully compatible with the ECMAScript 5 specification and is used in production in browsers and [node.js](http://nodejs.org)/[io.js](http://iojs.org)
+
+If you are looking for a low-level performance library for the server-side, note that node.js/io.js provides its own native module: [`crypto`](http://nodejs.org/api/crypto.html)
+
+## Supported hash algorithms
+
+* `MD5` (<http://www.ietf.org/rfc/rfc1321.txt>)
+* `SHA1` (<http://www.itl.nist.gov/fipspubs/fip180-1.htm>)
+* `SHA256` (<http://csrc.nist.gov/publications/fips/fips180-2/fips180-2.pdf>)
+* `SHA512` (<http://csrc.nist.gov/publications/fips/fips180-2/fips180-2.pdf>)
+* `HMAC` (<http://www.ietf.org/rfc/rfc2104.txt>)
+* `RIPEMD-160` (<http://homes.esat.kuleuven.be/~bosselae/ripemd160.html>)
+
+**Aditional functionalities**
+
+* `Base64 encoding/decoding` (<http://tools.ietf.org/html/rfc3548>)
+* `CRC-32 calculation`
+* `UTF-8 encoding/decoding`
+
+## Environments
+
+- Browsers (ES3)
+- node.js/io.js (all versions)
+- Rhino
+- RingoJS
+
+## Usage
+
+Each algorithm has its respective own instantiable `object`. Here you can see an example of how to create a new instance for each one:
+
+```javascript
+// new MD5 instance
+var MD5 = new Hashes.MD5
+// new SHA1 instance
+var SHA1 = new Hashes.SHA1
+// new SHA256 instance
+var SHA256 =  new Hashes.SHA256
+// new SHA512 instace
+var SHA512 = new Hashes.SHA512
+// new RIPEMD-160 instace
+var RMD160 = new Hashes.RMD160
+```
+
+An example of how to generate an hexadecimal-based hash encoding for each algorithm:
+
+```javascript
+// sample string
+var str = 'Sample text!'
+// output to console
+console.log('MD5: ' + MD5.hex(str))
+console.log('SHA1: ' + SHA1.hex(str))
+console.log('SHA256: ' + SHA256.hex(str))
+console.log('SHA512: ' + SHA512.hex(str))
+console.log('RIPEMD-160: ' + RMD160.hex(str))
+```
+
+### Browsers
+
+This is a simple implementation for a client-side environment:
+
+```html
+<html>
+<head>
+<script type="text/javascript" src="src/hashes.js"></script>
+<script type="text/javascript">
+// sample string
+var str = 'This is a sample text!'
+// new MD5 instance and hexadecimal string encoding
+var MD5 = new Hashes.MD5().hex(str)
+// output into DOM
+document.write('<p>MD5: <b>' + MD5 + '</b></p>')
+</script>
+</head>
+<body>
+</body>
+</html>
+```
+
+### node.js / io.js
+
+```javascript
+// require the module
+var Hashes = require('jshashes')
+// sample string
+var str = 'This is a sample text!'
+// new SHA1 instance and base64 string encoding
+var SHA1 = new Hashes.SHA1().b64(str)
+// output to console
+console.log('SHA1: ' + SHA1)
+```
+
+### Command-line interface
+
+You can use the simple command-line interface to generate hashes.
+
+```bash
+$ hashes sha1-hex This is a sample string
+> b6a8501d8a70e74e1dc12a6082102622fdc719bb
+
+# or with quotes
+$ hashes sha1-hex "This is a sample string"
+> b6a8501d8a70e74e1dc12a6082102622fdc719bb
+```
+
+For more information about the options supported, type:
+
+```bash
+$ hashes -h
+```
+
+### Installation
+
+Via [npm](https://npmjs.org)
+
+```
+$ npm install jshashes
+```
+
+Via [Bower](http://bower.io/):
+```
+$ bower install jshashes
+```
+
+Via [Component](https://github.com/component/component):
+```
+$ component install h2non/jshashes
+```
+
+Or loading the script directly:
+```
+http://cdn.rawgit.com/h2non/jsHashes/master/hashes.js
+```
+
+## Public methods
+
+Each algorithm `class` provides the following public methods:
+
+* `hex(string)` - Hexadecimal hash encoding from string.
+* `b64(string)` - Base64 hash encondig from string.
+* `any(string,encoding)` - Custom hash algorithm values encoding.
+* `hex_hmac(key,string)` - Hexadecimal hash with HMAC salt key.
+* `b64_hmac(key,string)` - Base64 hash with HMAC salt key.
+* `any_hmac(key,string,encoding)` - Custom hash values encoding with HMAC salt key support.
+* `vm_test()` - Simple self-test to see is working. Returns `this` Object.
+* `setUpperCase(boolean)` - Enable/disable uppercase hexadecimal returned string. Returns `this` Object.
+* `setPad(string)` - Defines a custom base64 pad string. Default is '=' according with the RFC standard. Returns `this` Object.
+* `setUTF8(boolean)` - Enable/disable UTF-8 character encoding. Returns `this` Object.
+
+## Hash encoding formats supported
+
+* Hexadecimal (most extended)
+* Base64
+* Custom hash values `any()` method
+
+## Benchmark
+
+Node.js 0.6.18 running on a VPS Intel I7 930 with 512 MB of RAM (see `server/benchmark.js`)
+
+```javascript
+Simple benchmark test generating 10000 hashes for each algorithm.
+String: "A0gTtNtKh3RaduBfIo59ZdfTc5pTdOQrkxdZ5EeVOIZh1cXxqPyexKZBg6VlE1KzIz6pd6r1LLIpT5B8THRfcGvbJElwhWBi9ZAE"
+
+* MD5
+** Done in: 205 miliseconds
+* SHA1
+** Done in: 277 miliseconds
+* SHA256
+** Done in: 525 miliseconds
+* SHA512
+** Done in: 593 miliseconds
+* RMD160
+** Done in: 383 miliseconds
+```
+
+See `client/benchmark.html` for client-side.
+
+## Notes
+
+* Don't support checksum hash for files on the server-side, only strings-based inputs are supported.
+* It has not been planned to include support for more hash algorithms.
+* The goal is to provide the same JavaScript code in both server and client side, so it isn't planned to improve it in other ways.
+* Only Node.js server-side was tested, so with minimal changes, you can setup `jsHashes` in other server-side JS environment.
+
