Spoike 82542ae037 Committing this before I break it any more. 
Massive terrain system rewrite.
Added a Native Client port (sound is stereo 44khz only, rendering is gles2, networking is websockets only (sv_port_tcp supports acting as a qw websockets server with non-nacl servers, filesystem is downloads-only - no saves/configs). Blame Zalon. Grr.
