OSX/SWT: Adding OSXUtil: RunOnMainThread(), IsMainThread() / Utilizing those for SWT access/calls

Adding OSXUtil: RunOnMainThread(), IsMainThread()
- Issuing a native call where the user Runnable is to be performed on the main thread
- Enable query if we are on the main thread.

Utilizing those for SWT access/calls
- Using the above to call all SWT functions on the main thread if required (incomplete)

TODO/Issues:
- JOGL OSX CGL Context fails, ie expecting NS, but having CGL
