Merge configmenu from extras with Configuration Panel module(after discussion with raster). For this, I added API to disable or enable any augmentation point from any module and later enable it again. Thanks to this merge, you can have configuration panel categories directly in main menu, replacing old items like Gadgets in that submenu. You can easily switch to old style from Advanced->Configuration Panel, if the module is disabled it is the old style of course. Also I removed configmenu from emodules when it is not needed anymore.
