Update 2017.1 - VS mode against an AI

GravPool has received a small update that adds some minor polish as well as a new mode. [list] [*] Play VS the computer in 3 different arenas [*] High scores table scrolls to support a longer list [*] Billiards fade as you near them enabling better visibility [/list] Further development is planned, though some of the modes I tried to implement just didn't really work how I wanted them to. Rather than work on a big release I'll be putting out incremental changes every so often.
