vicfg: New command, allows editing (or simply viewing) most of the repository configuration settings stored in the git-annex branch.

Incomplete; I need to finish parsing and saving. This will also be used
for editing transfer control expresssions.

Removed the group display from the status output, I didn't really
like that format, and vicfg can be used to see as well as edit rempository
group membership.
