Update 2017.2

This goal of this release was mainly to remove some debug messages that I had accidentally left in before. Whoops! However there are a few other tweaks as well. [list] [*] SteamVR plugin updated to latest version [*] Removed debug messages from game initial start [*] Menu billiards had not been updated to the newer shader and particle effects [*] In all modes except survival game type, you are now prevented from taking a shot if the cue stick is colliding with the walls or other billiards. You will have to attempt trickier shots in some cases [*] The ai is less predictable, though still not particularly smart [*] Survival game type starts in less claustrophobic arena [/list]
