Add alternative code for 1984/mullender for all!

Now anyone can enjoy 1984/mullender! This was a slight change to code
originally suggested in the faq (which was also updated, see below) made
for modern systems (since CPUs are much faster nowadays the duration for
usleep was much too long so one could not really enjoy the entry).

Updated bugs.md to remove this entry from the bugs.md file.

Also updated faq.md with another item. Unfortunately I had already added
another entry to faq.md and had failed to commit it before doing this
change (and adding it to the faq): how to get X11 entries (or actually
any X11 application) to work in macOS Mountain Lion and beyond. This is
why that faq entry is on this branch. It was not intended but it felt
like this change should be on its own branch / in a separate pull
request. I did not want to temporarily modify faq.md simply for this. I
have more changes to faq.md to make but that'll be on another branch so
that I have these changes there as well.

+## Alternative code:
+
+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) added the alternative
+code which lets you run this on other systems. He notes though that this was
+only a slight fix to the change in the [faq](/faq.md). Thank you Cody for your
