Fixed stacked calls when settings game states

Game states now processed into the scene update() call. This prevents from
stacking calls in setState() which resulted due to the event based
communication mechanism between gamemaster and playscene.
Set game fps to 40
Refactored HUD create/destroy in playscene
Added clickable animation object
