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. :)
Start "modernizing" the code base; old code is based heavily in the
Smalltalk style, where everything that doesn't return a different object
returns self. This can be useful, but it isn't what is usually done these
days. Also, add type information (which didn't exist in "the old days" --
an object was an "id", not a "Foo *") to help with debugging.
