[qwaq] Make the event system more informative

Doesn't have timestamps at this stage, but otherwise it reflects the
event system I had in my old text UI which was heavily based on
TurboVision. TV is pretty good (after looking at things a bit closer I
found it wasn't as deep as I thought), and better yet, Borland released
it to the public domain 23 years ago! (wish I'd known that).

Anyway, this commit gets something happening on the screen, even though
the current hierarchy is still a mess.
