Init Graphic subsystem to have the same tex filtering mode as engine.
The Engine parameter and Renderer has the default texture filtering mode set to trilinear. While the Graphic subsytem has it set to bilinear. This mismatch would cause unnecessary graphic API calls, especially on OpenGL, in the first frame.
[Added] Method to get and set a default camera on a scene for easy accessibility
Modified Sound to provide its own unique category for UI sounds
Changed way Log works to let the user open their own log and then engine will not override that.
[Changed] Updated CMake Flags
Merge branch 'feature/scene-default-camera' into development
