Team Fortress 2 changes

Attempted to solve various problems with jitter with player movement (particularly while crouch jumping)
Fixed possible cases of slightly misaligned hitboxes
Projectiles no longer spawn with an interp delay
Optimized threading behavior
- Removed overhead introduced in 0.1.10
- Waits on a single object no longer are forced into a full sleep state if they were already signaled at wait start
- Being signaled at wait start now forces a context switch to emulate sleep states entered for other types of waits, improving thread scheduling
- Removed all optimistic cases for thread waits, as they added overhead in most cases
Cleaned up preload files so that the game does not attempt to load unused or non-existent files on startup
HLTV now defaults to off in listen servers (can be enabled with -hltv in launch options)
