Add post_mkcamp_command hook

Add ability for a command to be run after mkcamp completes.
Adjust mkcamp to allow for the app init to only happen if you
have a app defined.
Added camp_config() hash key '0number' which contains the camp number 0-padded, so camp numbers less than 10 will have a leading 0 (like 07).
Merge remote-tracking branch 'localfilmmaker/tokens'
Reducing complexity in camp-info.

Simplified the mapping of options parsed by Getopt to database fields for camps for display.
Removed code related to option aliases that are not documented or are redundant and confusing.
There is no other field that makes sense to set except for comment, so removed unneccessary code abstracting that out.
Added option -A to camp-info script to display all camps on the system similar to the listing from the cgi-bin/ index page.
