gmg wipealldata fails if you don't have mongodb

[Will Kahn-Greene]

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.

130 (M=d2eab local) saturn ~/projects/mediagoblin> ./bin/gmg wipealldata
*** 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
  things properly on the default setup!  If you've customized
  your mediagoblin configs, it won't work (for now).
Are you **SURE** you want to destroy your environment?  (if so, type "yes")> yes
nixing data in mongodb....

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.

This command doesn't really work at all anymore with our new setup I guess?

It might be useful instead to have a copy-pastable bash string on the HackingHowto that can show you how to wipe your data for a test install.

Should be something as easy as:

rm -rf mediagoblin.db kombu.db celery.db user_dev mediagoblin_local.ini paste_local.ini

... mayyyybe minus the _locl.ini files, not sure.

I updated this and think I'm fine with the solution at:

... closing this out for now.

I concur. That solution works super. Yay! :)
