macosx gui: Fix resetting of the prefs.

Ok, this isn't making it much nicer, and this code definetly needs a more careful rewrite, but this is patchwork for the 1.0-bugfix release and at least it will do for now.

- reset's the values in any loaded views after reset of the config is called
- does not reset the module selector atm. might follow later on.
