Patch 5

Apparently NTT v100.033 runs draw_pause during boss intros.  I've added a simple fix to only create the options menu in draw_pause if there has previously been a PauseButton present while "paused".

This should be good enough unless you have a mod doing something weird like creating the retry button during boss intros or deleting every button when you pause so you can only /exit.  Really no one should be doing that, and if they are they should expect things to break, because it's weird.
