rewrote tab completion logic. should no longer consume so much cpu time.
added tab-completion for the connect command. server lists must have been requested previously (like the connectbr command requires).
fix q1bsp fencetexture+fog combo.
fix wateralpha/lavaalpha/slimealpha/telealpha worldspawn fields.
added a couple of extra cvars to some rulesets.
fix d3d9 mipmap-size issue.
fix vid_reload issue (was crashing, but its also possible that it could have been the cause of VBO corruption).
made pausable default to empty, allowing for smarter defaults like pausing SP but not DM.
attempt to compensate for NQ's framerate-dependant waterjumps by making QW waterjumps slightly more permissive.
