*added refresh of partition size when activating wii games mode from none wii games mode
*fixed playback of some BNS banner sounds
*moved every allocation used during or after apploader to mem2 (fixes some memory overwrites problems by the apploader)
*improved detection of game partition when starting the loader without configs (fresh start)
*fixed remove of unused cached titles on wiitdb load
*Moved all related global settings to a settings class. one for themes and individual games will follow. Probably broke some settings or theme loading, we can deal with that later and fix when someone discovers bugs.
