OSX Fix: Catch releaseImpl's glFinish() exception (DebugGL); Make GLContext.release's setCurrent(null) exception prone.

Catch releaseImpl's glFinish() exception (DebugGL)
  glGetError() after glFinish() (eg. w/ debug pipeline) produced unknown error 0x0506
  on OS X (10.7.2 NV).

Make GLContext.release's setCurrent(null) exception prone
  Call setCurrent(null) in finalizer block to ensure it's 'released' out of the TLS
  even when an exception is being thrown.

Make MacOSX Shared Resources 'destroy' more error prone (catch exceptions)
