This MR changes the behavior of applications logo.
When it contains a dot (.), nothing changes, the logo is considered to be an image file.
When it doesn't contain a dot, it is treated as a Font Awesome icons, with special template processing.
Example, replacing default LLNG icons with FA icons:
Manager UI has been extended:
with dot:
without dot:
a help text links to the list of Font Awesome v4 icons:
Implementing this change required adding font awesome to the manager.
I did not update Font-Awesome version because the version provided by debian is stuck at 4.7.0, we should discuss this separately. Of course, a custom portal theme could use any higher version, or even a different icon pack
