Minor fixes 2024-02-19

Folks are already reporting bugs! Thanks for the help testing.

• removes everything that could possibly write to the clipboard, the “finish copy” messages should stop happening now and if they don’t I’m really baffled
• fixes crash on the title screen after a few minutes

That second one happens because the title screen is just an arcade level with a weird configuration (you can jump and dive on the title screen! try it!). It was intended to never emit words, but I was resetting the wrong variable every frame and the actual frame counter kept cheerfully counting down from its initial value so after 9999 frames it dutifully tried to draw a word and, finding no word list, crashed. I fixed the timer reset.
