Sources & Anchors

I have added credits for more sources as well as anchor links. 

Anchor Links:

in each section of the ``` index.html ``` file, i have added an anchor link named after the section's name, for example: the buttons section has a anchor link that looks like ``` <a name="buttons"></a> ```.  With this, you can skip right to a section going to  http://benfields.github.io/Effeckt.css/dist/index.html#buttons .  


Credits:

I have credited [animate.css](http://daneden.me/animate/), [Ugo Quaisse](http://codepen.io/uquaisse/pen/Jqhte), as well as [myself](http://codepen.io/benfields/pen/Bkhlv) (ben fields) for the contributions and code that has been used in Effeckt.css
