Clean-up CSSValueKeywords.in

This change started as a removal of stale entries in the file
(mostly related to font-stretch - that was rolled out - along
with some misc values).

Then I looked at the file and found out that we still referred
to KHTML and CSS_PROP* (none of which make any sense) so I
cleaned up the comments too.
