Icon refacto

 Refacto icon font. Now font is compiled from svgs

Instead of a predefined font, a list of svg are available in a folder.
The resulting font and icon classes are compiled from this folder.
This means you can easily remove, rename, or add an icon to ev-fdm.

This file seems to be the original (not a compiled one). Maybe consider remove this comment.
