Given that we don't need mongodb things installed anymore and we're removing the installation instructions from the documentation, it shouldn't be the case that tests fail if you don't have it installed.

These tests should get fixed so that they get skipped if mongodb is either not installed or not running. nose is super duper for this sort of thing.

If you run ./bin/gmg wipealldata, but don't have mongodb installed or running, then it kicks up errors.

Given that we're done with mongodb, this should handle the cases when mongodb isn't installed or running.

*** WARNING! ***

Running this will destroy your mediagoblin database,
remove all your media files in user_dev/, etc.

ALSO: This command is currently a hack and will only remove

Seems like this should be a blocker, too, since it's referred to in the Hacking HOWTO, but ... I'm going to just make it Critical.
