Remove debug logging and add negative texture cache to fix lag spikes

Browse source 
Remove PPM composite dumps, MODEL1_BOUNDS vertex analysis, TEX_REGION
logging, FOUNTAIN_PARTICLES debug output, and verbose chat/warden gate
logging. Add negative cache for failed texture loads to prevent repeated
file I/O for missing textures like deathknighteyeglow.blp.
