Changed the name of font-awesome for correct package

I get small conflict with font-awesome:

bower uninstall fontawesome --save
bower conflict      summernote depends on fontawesome
[?] Continue anyway? (Y/n)

The oficial package is "font-awesome", not "fontawesome". For not keep both is better set the correct name.
I though `fontawesome` is right. There is no `font-awesome` in bower search results.
