Toggle Fullscreen working

Got toggle fullscreen working in option menu. Also fixed the transition
from gameplay screen to main menu.
Character tweaks to make them more varied

Made enemy physics update even after death. I think I stopped bug that
made player move when celebrating and when dead. Changed speeds of all
characters, overall everyone is faster. Changed health of heroes, they
are different. Hero flight jumps higher.
Merge branch 'feature-toggleFullScreen' into development
