ok, it's implemented know and seems to work fine. i'm thinking about 
additionally let MustuxGlobalProperties emit a signal when a specific 
key changes... so you can get notified in a more QTish way when a key 
changes, and that won't required to have static callback functions.

other change which have to be done in MustuxGlobalProperties since it's 
in libmustux now:
in MustuxGlobalProperties::init(QString rcFilename), the 'default value 
setting' code which initializes the dictionary when no rcFilename file 
is found, should be removed, as it's the application's job to do that.
Mustux can't know what default key and with which value a specific 
application will need. So init() should return false when no file is 
found, so the application will know it has to set the default values.

ok, now i think it's again time to work on autostuff, and writing one of 
the last piece of the puzzle: a good qt m4 macro well suited for mustux' 
need.
