Merge of Reveal.js With FontAwesome Framework

made the Fontawesome Framework fit to suit into your reveal.js Framework.
Thought its a nice way of having scaleable Icons already at hand, and they suit the style of the general reveal themes very well.
Added on the second slide a rotating spaceship as quick example that it works. (included those in the index.html)

(Not sure how to add the FontAwesome Guys into this pull request.)
