between drones are not always being resolved correctly

getting game to work

need to commit before merge
updated death-check in element

and moved some code around
fixed circle_circle bug by creating new vec instance lshift in reaction.coffee

fixed the bug
created Drone class for dronewar, fixed some bugs and refactored reaction/death

a lot of updates but mostly related to abstracting dronewar-specific
game details into the base classes i.e. element.death_check(), death()
etc. and added Drone class to dronewar (extends Circle class)
