Change shebang lines from /bin/sh to /bin/bash.
Add 'arp-ip' and 'qnmap' to Makefile.
Update TODO.
Remove debug print in 'git-wc'.
Change arguments used in 'def'.

Only the first argument is made part of the query now.
Make small, unimportant changes in a number of scripts.

None of these changes affect script behavior. Most of them are things
like line splits and joins.
Combine list and help in 'translate'.

Before, there was a flag to list language and a flag to get help. Now
the help flag does both.
