font-patcher: Allow patching of True Type Collections
[why] Someone might want to patch a whole lot of fonts that come in a ttc. [how] Just open all fonts that the input file contains (1 or more) and create a single font or collection font file. The automatic layer detection does not work in all cases for me, so we need to manually search for the foreground layer (usually '1'). Code inspiration taken from https://github.com/powerline/fontpatcher/pull/6 [note] Changed output in the end to the filename (before it was the font name), so that one can easily copy&paste or open that file.
