	Normalize all our custom properties in our implementation to be -khtml (remove all the -apple).

	Make sure that -apple, -khtml, and -moz are all able to be used.  -apple and -moz just map to -khtml.

	Add support for automatically converting -khtml-opacity to opacity (for legacy Safari 1.1 compat).
