I've been thinking about auto-building qix files... it would fix this

I think programmers will hate the idea, but users, maybe they will
like it? What do you think?
You guessed right... I, as a programmer, am not keen on that kind of
magic behavior. I like to think of dataset access by MapServer as a
read-only operation, for security and various reasons I would not want
to allow write access to the data dirs. But I'd be happy to see a
"Mapfile optimizer" tool that does this kind of stuff.
BTW, a step we could easily take in the short term is add a msDebug()
message at level >= MS_DEBUGLEVEL_TUNING warning users that a given
shapefile hass no .qix and adding one could increase performance.
There could also be a test added at the same debug level and if the .shp
file date is newer than the .qix then produce a warning saying that the
.qix may be out of date.
