redis key info is essentially backwards

[jvanasco]

so there is this bit in redis_.py

def _format_key(self, key):
    return 'beaker:%s:%s' % (self.namespace, key.replace(' ', '\302\267'))

That generates a key like this:

beaker:f1d17960690c49a9807e5b4c2e29afd3:session

but one might expect

beaker:session:f1d17960690c49a9807e5b4c2e29afd3

If this was intended, there should be a note to let people know how/where to look for their data.
