Sample tests

[staxmanade]

I commented earlier on #2 and threw together a quick sample test using Approvals.

Note 1: it would be better to use something like Jasmine or Mocha (I like Mocha) to set each test instead of a single node.js script - but it's the simplest thing at the moment.

Note 2: I was struggling with line-endings. I put a simple .gitattributes in and re-set the files. I tried to make the commits meaningful. While looking at the diff of all won't help (due to line-endings changes). other commits should give context of changes.

Note 3: Would be good to put other sample data/posts into the test and verify the output is correct (saving the *.approved.txt files.

If you merge this commit you could then run npm test to execute your tests.

Hope this helps.

Feed validator test should pass with staxmanade@0081a85.

I've referenced RFC and Wikipedia example.
BTW it seems like link tag with rel="alternate" attribute doesn't need to be generated since link tag without rel attribute is already generated from same options.link.

@staxmanade Thanks for the update.
Having tests is nice. :)

This pull request has an impact on two many files - it seems like you've overidden the indentation at the same item.
