Upgraded fontawesome CSS 4.1.0 -> 4.2.0
Added Fastclick JS library.

This library should eliminate the 300ms delay in touchscreens. This delay is intended to make sure the user is not double-clicking, but in apps like this which use no double-clicking it just makes the app feel unresponsive.

Fastclick is supposed to attach no listeners if it's not needed (e.g. in desktop browsers), so no loss of performance is expected.
