Din's Legacy - Performance Improvements

• fixed long loading times on some maps (Doesn't Learn From Mistakes/Destro)
• moved ogg decoding to own thread (music and 2d sounds) - should be a bit faster and allows music to play during loading
• now static models (1 animation with 1 frame) always go down static vbo path (test went from 50.8 to 60.8 fps)
• now all dead monsters of the same type shares the same vbo (test went from 66.2 to 71.0 fps)
• fixed addObject in spawnAreaBlock to not reference modelResource so much less likely to pause waiting for resource to load
• fixed effects being generated in light and shadow mapping passes (speeds up test from 48 to 60 fps)
• no longer sort draw surfaces in normal draw and shadow mapping pass (already sorted in light pass)
• fixed explosion precaching not working correctly
• improved projectile precaching
• now make sure don't get in an infinite loop when precaching (don't think it has even happened yet, but as it gets more complex it would happen without protection)
• now precache hazards
• now precache objects
• precached a bunch of small things better
• now precache swipes better
• hooked up 4 new mail/plate male player skins
• now precache money sound and soulstone model
• now precache footstep sounds
• now precache basic elemental effects
• precached status effect assets better
• now precache level ambient objects
• fixed a bug in PlayerClient::getTitle that might have been causing a rare Character menu crash (eddieray7)
• fixed music not playing in menus
• sped up StatusEffectBase:rocessDatabaseEntry (test went from 23 to 12 seconds)
• now more particles combine into the same surface - speeds up particles a little (4% in stress test)
• now gameShared->getPackedDatabaseEntry uses database hints - should speed up loading some
• fixed PlateSteel_d.tga being wrong tga type (prevented it from being compresses and included in public build)
• no longer calculate hash multiple times for DatabaseEntry::getAllValues type calls (overrides/addsTo/base)
• now when looking up each database entry base, uses the hint from the current subdatabase to speed up search
• fixed infinite loop if change SERVER_FRAME_TIME
• can now change the server frame time with serverFrameTime user var (default is 50)
• fixed on old whirlwind effect being referenced
