Allow psql_camp to work with manually specified camp0
Add script to run ungit in a camp: https://github.com/FredrikNoren/ungit
Add db_source_scripts_parse option to local-config

When files listed in db_source_scripts also appear here, interpolate any
tokens found in them such as __CAMP_NUMBER__.
Quell an uninitialized variable warning
Replace, don't append to, my.cnf when refreshing camp databases
Make user management more flexible

Previous system has 'interch' hard-coded within the
validation routine, requiring the entire validation routine be
subclassed to change the user (which also required pulling in
User::pwent to the subclass). Also required re-working the
validation routine if more than 1 user might be valid.

New setup allows just the list of users to be subclassed, similar
to adhoc_base_path and adhoc_ic_path. Further, assumes any number
of valid users to be possible. Doing nothing is fully backward
compatible with current setup, including any subclassed overrides.
Updated _initialize_camp_database_mysql() to use the camp's my.cnf.

When running mysql_install_db pass in the generated my.cnf for the camp to make sure it uses the camp settings.
Added several new command line options to the re command
