Obtaining a font has become rather expensive in recent gnustep, so cache
fonts, obtaining new ones only when needed rather than every redraw. Makes
things snappy again :)
Add return-type information to all methods, split up lines properly where
I could find them, and ran the whole thing through uncrustify. Looks purty
now. :)
However, it still won't work (no gorm, commented code, ...).
Borrow an old implementation of the Storage class until I figure out just
what it's being used for.
