StateEngine Dummy implementation + Collision detection + BugFix SimpleButton (creates Memory Leak :D )

->Collision detection does work no ( hopefully ) further testing
required
-> Dummy implementation of a StateEngine ( not tested yet / no
functionality yet)
-> BugFix (Programm crashes at the end ) by creating the string and text
of ClSimpleButton via new without deleting them
