Mhotar/proportional fonts

It seems to be ready to merge.

[All] Proportional fonts
[All] INVERTED texts are nicer, it means they have black surrounding from all sides.
[ All but M64+FRSKY] condensed_bold_font file used to create BOLD characters
[All] x-coord prefix available to be used in translations strings
[CPUARM] NEWLINE flag available to be used in translations strings
[All] Active switch suffix display fixed in Custom Functions

TODO: some CENTERed strings in translations files are now shorter a bit, so they have to be altered a bit.
