We need a way to identify bitesized bugs in redmine.

More specifically, we need to:


1. "tag" an issue in some way so that it's clear it's bitesized
2. trivially query the system for all bitesized bugs

This gets progressively more important as we continue to get new
contributors.

I'm going to make this an Immediate priority for 0.0.3 to at least
look into more. If it's the case that we can't do this, then that's
a very compelling reason to switch to another bug tracking system.

The documentation currently uses the standard python-sphinx
theming, but should be better integrated with the rest of
mediagoblin.org.

Currently we have status being one of "active" or
'needs\_email\_verification'... we could simplify things by just
having email\_verified (which we already have) and "active" be a
boolean.

The role of active will then switch to whether or not the user is
enabled. You might set active to False if a user was abusing their
account, for instance.

The migration on this should be pretty easy... just remove
needs\_email\_verification and make all existing users active,
since currently we don't have any inactive state.

This is a bitesized task.
