WIP New "--uifont" option to specify UI font

Browse source 
If not specified, or "default" is specified (e.g., to override
a higher-up config file setting), it will fallback to what we
have #define'd in fonts.h as PANGO_DEFAULT_FONT, "DejaVu Sans".

It appears to fallback to this (or a reasonable fascimile) if
the font specified by the "uifont" option doesn't exist
(e.g., "tuxpaint --uifont=ABCD1234").
