Team Fortress 2 changes

Made context switch return immediately if there was no thread to switch to
Greatly optimized thread events:
- Waiting for 0 seconds (just initial check) no longer enters a sleep condition
- Fixed many more cases of freezes, which allows for restoring the more optimal infinite sleep condition state
- Waiting for all events now does not take another, recursive lock in order to handle event listeners
Greatly optimized sound loading from cache to correct order of loading and reduce redundant cache interaction
Implemented Steam Chat filter button in advanced options
- Fixes advanced options not displaying options past "Enable text chat"
- Button is implemented with improved style compared to live TF2
Fixed various issues with the game alt-tabbing on startup and map loads
- Fixed 3 redundant material cache + resource eviction upon map load
- Fixed HDR being off on game start, causing HDR to be initialized upon loading an HDR map
- Fixed mat_debugalttab not reporting anisotropic filtering values correctly
- Fixed the initial window resolution set causing Source to think the resolution changed, which makes it reinitialize the window a second time
- Fixed anisotropic level being reset back to 1 and then back to the original value some time later when the render state was reset on init
Made evict managed resources queued (taken from CS:GO)
Enforced hardware sync even if the render thread finished quickly on the CPU

Team Comtress 2 fixes

Cleaned up launch .bat scripts
Fixed some issues with fixed recoil spread
- Fixed recoil spread was enabled even when there was no fixed seed
- Fixed Minigun recoil spread seed not being per bullet when fixed
- These two issues being fixed should resolve Minigun accuracy problems
Removed new shader pathways introduced in 0.1.4, as they were faulty
