Revamp Player vs Monster collision code. Add in handling for solid objects causing the player to run against the object instead of bouncing off of it. Make solid monsters (pillars) have transparency like foreground terrain when looking behind them. Add terrain collision boxes for these as well. Release Build 9610.
