Add various TODO notes
Delete language files of deleted acp parts
Delete Pacman files, as these aren't GPL'ed

Maybe there's an other solutions, but I fear this game can't be included with a
GPL-licensed program without further notice. This is the easiest way.

As an alternative to the default game, the README.txt has been rewritten and
contains an extra step to add some games.
Delete code for themes and templates
Finish conversion of xmlhttp code

Note the fact that the Game Section session isn't initialized,
as it isn't used in the code.
