./bin/gmg shell mediagoblin.ini

should launch a shell with:

• mediagoblin.globals set up and pre-imported as mgoblin_globals
• "mgoblin_app" instance set up, an instance of MediaGoblinApp
• a bit of text is printed out explaining that those two variables are available

Currently we embed the User object into the MediaEntry field. Bad, bad bad! This means all sorts of terrible things, but especially that we'll be keeping potentially out of date information. We should be referencing it instead.

On registration you can register a new account even if there is already a user with this name (but with some letters lower/uppercase).

An example: There could be a user "alice" and a user "Alice" at the same time.
