Fixed all currently known issues and rewrote a majority of the code.

Removed unnecessary materials

Added new "Ballin' Single Use" SWEP that removes itself after being thrown, but is able to be regained if you press E on the thrown ball.

Added new ConVars:

ballin_ballsize - 1.3
ballin_ballmass - 1.0
ballin_ballforce_multiplier - 1.0
ballin_jumpforce_multiplier - 1.0
ballin_trailcolor - "255 255 255"
