patch: qconf "help" menu

Okay, so I'm a moron.

The first time I upgraded from 2.4 to 2.5.47, it took me half
an hour to figure out how to turn the PS/2 mouse back on
(serial I/O was off, so I couldn't see it.  Doh!).

But I figure I'm not the only moron on the planet, so here's
a patch that adds a help system.  Simplest, most brain-dead
implementation possible; all inline strings, no internationalization,
etc.  I figure it was worth an hour of my time to save some
other morons' hours.

P.S. Apologies if Lookout barfs on the long lines.  Crossing
my fingers...too embarrassing for words to be using it...
