Fix for back

[Wolfgang Lux]

Hello again!

Just another fix for back, which makes the backend respect the
UseWindowMakerIcons, GSAppOwnsMiniwindow, and GSDoubleParentWindows
user defaults. The problem is that NSUserDefaults' -stringForKey:
method returns nil for a boolean value. This is probably a bug
in base (haven't checked on Cocoa though). However, it doesn't
harm to use -objectForKey: instead of -stringForKey: anyway.
