	Reworked lists to work well with RTL text.  Specifically the following bugs have been fixed:

	(1) All bullets use the same offset constant now (a padding of 7 pixels).  Before, images used 5 and others used 7.
	(2) Line height now works properly, so that list items with no content aren't squished (and missing the line descent).
	(3) Punctuation now works correctly with inside and outside style ordered lists in RTL.
	(4) RTL lists now properly apply padding and margin to the right side rather than the left.  This was done by adding
	-khtml-margin-start and -khtml-padding-start properties that are just mapped to left/right based off the direction.
