Fix my own errors in aquarela(8).

Fix reference to 9fs with reference to srv(4), so the link 
works in html representation. Fix reference to Unix
nmbd(8) so programs don't make a manual reference
out of it.

Updated DESCRIPTION to reflect better understanding.
Aquarela won't (that I see) check first if /n/share is
already a mtpt, but instead just tries `9fs share'.
Completed list of UDP ports used under -n.

Alphabetize options table instead of sort by relevance.
Fix double-quoting of `foreign' words to single quotes.
Surveyed existing manual pages and this seems more
common. Same for UNIX into Unix.
