Enables more fields on items besides default and more namespaces in XML RSS Header

[ghost]

Feature 1: Enables to add your custom fields on every item, since only default ones where parsed and included. Originally you can add just the following fields:

  title
  description
  url
  guid
  categories
  author
  date

To add more fields, just define them in the item creation, like this:

  feed.item({
              title:  'item 1',
              description: 'description 1',
              url: 'http://example.com/article1',
              date: 'May 24, 2012 04:00:00 GMT',
              'myClass:otherField': 'f06057b8b5877e75e7333074cc057e4d'
          });

Feature 2: Enables to add more namespace definitions into the XML RSS Header using the function xmlAddAttr (attrKey, attrValue). For example:

feed.xmlAddAttr('xmlns:myClass', 'http://www.example.com/myClass');

renders to:

<rss xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:myClass="http://www.example.com/myClass" version="2.0">

Running the tests

Step in the root of this module and run:

$ nodeunit test

You should get:

$ nodeunit test

test
✔ empty feed
✔ easy test
✔ easy test without image_url
✔ easy test without image_url with extra fields on items
✔ easy test without image_url with extra fields on items and an extra XML RSS Header

OK: 10 assertions (15ms)

(If you don't have nodeunit, do like below)

$ [sudo] npm install -g nodeunit
