Thumbnails: Add translations to font preview.

Not much to say, this is pretty straightforward.
We just have to add current locale to thumbnails 'signature', so that
previews get re-generated when we change locale...

Tested with Japanese and French.

Btw, I do not really understand why using BLF in ImBuf is badlevel... :/
