Added some psuedo examples to upgrade-implementation.
Fixed problem where combo timer would not update. Delta was not being passed to Field.updateCombo.
Removed bpm.state.current; passed states to dbg.addCheats.
Issues #35 + #45 Fixed Field.setWeapon();

currentWeapon was being stored in bpm.player; changed so only a string
gets stored. This was also the reason for the ammo time freezing between
rounds.
Updated responses on ice plan
I#35 - Fixed switching to the same weapon bug
Adding in ice - apply finished
