Added config warning for ops on login

Now Muni will warn the ops when the config version is out of date upon
login.
Minor Changes

Comments mostly, including GPL notification and comment headers for many
of the new files.

Added voting and wg module opt out logic in muni.  WG opt out needs to
be carried into existing WG functions, whereas voting needs to be
designed around it.

Rearranged some things in the Muni main class for readability

Removed some old debug functions, including the ability to create a
database all willy-nilly.

Added the yellow chat color to the muni login messages.
