-Disable Start button in final render dialog when Pause is clicked.

--Bug fixes
 -Rapidly changing spinner values was causing the OpenCL renderer to report a failure, when it was really just aborting.

--Code changes
 -Renderers never internally set abort to true due to a failure. Abort is only set to true by the calling code.
