Added the rudimentary scoping ability.

There's lots more to do, but for now, it scopes upwards, keeping the laser
relative to the actual mouse cursor position. It also disables motion
while scoping.
Fixed the merge error...?

Also, the laser jumping error apparently. I don't remember doing this
though...
Is level okay now?
Please work?
