FontEditor: Update editor to handle new font format

Browse source 
The editor now unmasks fonts on load, mapping their glyphs to the
complete unicode character set, and masks them upon saving to
reduce disk space. This is a naive approach in terms of memory
usage and can be improved but whose immediate goal is to allow
editing any glyph without concern for range allocation.
