Juju is forcing *ALL* charms in a repo to be perfect to be able to deploy *any*

I have a number of half-done charms and not really working charms in my repository.

However, I can't deploy the working charms because juju is parsing *ALL* of the charms and completely dying because of one bad charm. This is completely bogus and needs to be reverted or handled far more gracefully, as I expect quite a few charm developers will be very confused by behavior like this:

$ juju -v deploy --config /tmp/myconfig.yaml local:statusnet
