acc, set, applet_oe: stub various functions, add set service (#105)

* Stubs for various acc:u0 funcs needed

* Stub for GetDesiredLanguage in IApplicationFunctions

* Add set service + stubs needed for games

* Fix formatting

* Implement IProfile, IManagerForApplication, return bool in CheckAvailability, style fixes

* Remove IProfile::Get(needs more research), fix IPC response sizes
