Create confadmin

[ccowart]

A la svnadmin, we need a confadmin.

Initially, I think this will only have a setup command. This would do
all of the svn mkdir stuff, including the checkpoints and meta directories.

The future plan is that this would also have amigrate or upgrade style
command that detects old versions and migrates the repository as needed.

(In [310]) Skeleton for confadmin plus related svn ignores and autoconf configs.

See #20

(In [315]) Wrote initial setup code.

The help and usage statements are still those of confman and not confadmin.
This will need to be fixed before this ticket can be closed.

(In [323]) Refactored sourcing of the documentation library to support the confadmin
utility. Cleaned up handling of -h for these scripts.

Also set the keywords property on source files that were missing it.
