Bootstrap3 : upgrade fontawesome (from 4.01) to 4.03 + cleanup icons name

I've upgraded Font Awesome to the latest version 4.03

I've also cleanup (delete, rename) many icons that were still using the old 3.x name.
I've processed the icons from letter A to H (will do the rest later).

I've added new 4.x icons.

On the FontAwesomeIconTypeBuilder.java I have only changed the enum FontAwsomeGraphic. I don't know why the PR considered I've delete all the file content!
