Made the editor use the new _controlupdate scheme, expect turbulence.

Removed a majority of the reliance on love input handlers.
Commented out game_* handlers to later be integrated into mario.lua
Moved portalknockback code to shootportal.
Transplanted mousepress signals from the editor to main so that they can be integrated easier.
Fixed mario being able to powerup while animating, causing glitches.
