small fix to build rule "index": creates tw5fontawesome.html; index thus is a generic rule name now.
Ignore me ... ignore me...
Added graphics image of fa-flag as a signet for Font Awesome to be used
in README and other documentation (fallback).
master/origin to master branch sync ... oh well
Merge branch 'master' of https://github.com/TheDiveO/TW5FontAwesome
