Cappuccino Cappuccino

Implemented token field overflow support as in Cocoa: if more tokens than can fit are entered, they wrap to a new line. If the new line does not fit within the height of the token field, the previous line is scrolled out of view.

Note: this replaces the previous non Cocoa behaviour where the token field would grow height-wise with new tokens. This behaviour can still be useful, as seen in Apple Mail, but it will now require the user to subclass CPTokenField, override layoutSubview and set the frame size to the size of the scroll view's document view.
