[RFC] NSTabView* rewrite (patch)

[Michael Hanni]

Hi,

I've completely rewritten my previous rewrite of these two classes. The result
is a much better implementation of both, including such things as: all tab view
types are supported; re-sizable tabs and view; better handling of tabviewitems;
works in Gorm; documentation; and many other things. In fact there have been so
many changes and additions I can barely remember everything.

There are still a few things to implement: NSPressedTab; finalize the
appearance of the tabs in all directions; and, most critically, the
initWithCoder code.

I'd appreciate comments regarding this code -- especially with regard to memory
management and the NSCoder bits.
