were "saved" to kmailrc, but kmailrc wasn't synced, so in case of a kmail crash, X crash, power failure, kernel oops...
the settings would be lost, and on the next kmail restart very strange errors would happen when syncing
(can't create folder, folder already there, folder missing, etc.)
The solution: sync(). But while being at it I implemented buffering of sync requests
which was a TODO in kmkernel, but did it in GlobalSettings as Till suggested;
which in turn means we need our own GlobalSettings inheriting GlobalSettingsBase,
and the code lacked ::self()-> in many places to allow that.
srcdir!=builddir users: don't forget to delete globalsettings.{cpp,h} from the builddir
since it's not generated anymore!
