FontEditor: Improve error handling opening, saving and editing fonts

Browse source 
Adds fallible functions for opening and saving fonts and cutting
and copying selections. FontEditor now falls back on a guaranteed
default BitmapFont on startup. Fixes crashing on start when the
default system font is set to TrueType.
