Fast button Fix 

This fixes [issue 96](https://github.com/centralway/lungo-angular-bridge/issues/96), implementing FastButton inside of Lungo's namespace.

Commits show where the bug happens (making first element in the aside an anchor) and the proper fixes, so changes to the dist folder were also made to show it.

Extensive comments were added to explain most of the things done. This is just a port of https://developers.google.com/mobile/articles/fast_buttons implementation, plus some extra changes like adding custom element in mobile devices only and some IE8 < polyfills for Window Phones (I know right?)

Feel free to remove the comments for cleaning purposes, although I'm guessing a uglify task already does that.
