Bug fixing

fixed a bug on LampMinion that caused it to respawn weird
Fixed a bug on shooting minion, wasn't facing right correctly
Changed player's shoot method to run on a timer instead of the 'One
bullet' thing
Fixed Wall, now functions as a ceiling too, and no longer has redundant
code!
(caution, ceilings will not work without more than 2 spaces from nearest
floor, simply because player jumps too fast)
Added Purple cheat :D
