fonts: fontawesome integration: Include parts of fontawesome free "for the web" 6.6.0, which will be used for icons in frontends to replace fontello. Fontello is not maintained anymore (last commit 2 years ago), and has licensing issues (some icons were advertise as free while they were not). It will be removed from this repository, and fontawesome is used instead. Only the parts actually used in Libervia frontends are included, to save space.

These pictures come from Crystal clear, were made by Everaldo Coelho (www.everaldo.com) and YellowIcon (www.yellowicon.com). They are under LGPL V3 licence (see COPYING.LESSER).
