- I did a pass over all .mm files in WebCore/src/kwq, adding
	actual return values for all functions that return something
	(there were *many* cases where callers were left dangling).
	- I added numerous log statements throughout the code.
	- I made the log statement system configurable at runtime, so the
	amount of logging can be increased or decreased as desired.
	- I added an implementation for QVariant.
	- I cleaned up the implementations of QBrush and QPen.
	- I made general fixups and cleanups in various places.
