General Improvements

**Head Tracker**
- Makes head tracker distance based
- Makes circle an outline of a circle rather than filled
- Adjusted circle to be more oval shape to fit character heads
- Added toggle feature to head tracker as requested by many

**Handle Hijack**
- Changed permissions for hijacked handle from all access to permissions of svchost.exe, which still allows read and write memory, but removes the all access permissions, looking more "legit" to VAC

**Offsets**
- Update offsets for game build 13968
