Fix endless loop when configured layout cannot be loaded
Review Request #128279 - Created June 23, 2016 and submitted
Adjust the configured layout when the default is loaded as fallback.
Otherwise loadSettings() will think that the layout has been changed in the settings, load the layout again and call startNewGame(), which in turn calls loadSettings() again, resulting in an endless loop.
Set an invalid/inexistent file for Layout_file in kmahjonggrc and run kmahjongg.
Before it didn't even open a window, now it starts fine using the default layout.
