Improved sound loader and bugfixes

- Static OGG loader now uses unmanaged memory and has a much higher performance
- Added realloc binding to join malloc and free
- Removed remaining debug print statement from the GLFW binding
- Added Timer.SleepUntil: polls a function until it returns true. Useful with SoundEmitter.IsStopped.
- Fixed directory:FullyLoad from the Coeus core
