XDarwin TM cleanup

[Torrey Lyons]

"XFree86" was liberally sprinkled through all nine localizations of 
the XDarwin UI. I have cleaned this up so there is no more mention of 
the XFree86 trademark except in the credits, which gives the wording 
requested in the 1.1 XFree86 license.

Unfortunately, some of the localizations are something of a hatchet 
job since I only speak one of the languages. I had to insert English 
sentences in the middle of foreign text and "X.Org Foundation" 
occasionally became "X.Org Project" where the the word "project" had 
been translated and I couldn't tell where words began and ended 
(Japanese). Oh well, you can't make an omelet without breaking some 
eggs.... I will alert the XDarwin translators, but I doubt they will 
have finished anything in time for the release.
