These changes fix the HD-Mode lag and crashes that happen when the client is launched into HD-Mode or when changing into HD-Mode..

Browse source 
In Windows, on first launch into HD-Mode or at launch going from SD-Mods to HD-Mode, the CPU maxes out and music issues, and is unable to enter into HD-Mode without lag or  multiple crashes.

This is because when the code that is supposed to execute GLProfile.initSingleton() waits for its turn on syncronized function queue and then a while loop keeps sleeping the thread until a status code of 1 is returned. Additionally, starting with jogl version 2.0 GLProfile.initSingleton() is not even necessary as its automatically done.

The code commented out has no purpose other than just to execute GLProfile.initSingleton().

Commented out the code and made comments to preserve the original code.

* Code below tries to trigger GLProfile.initSingleton() through a queue in PrivilegedRequest where it waits

* lag and delay when switching to HD Mode.
* GLProfile.initSingleton() is automatically run starting with jogl 2.0 and later. So no need to execute it.
* After it returns status code 1, it also sets an important variable aBoolean73 to true
* when the queue executes successfully.
* This triggers the needed GLRenderer.init() function which we can control to be true manually.
