Sort out branch/fork situation

[ejucovy]

The branch/fork situation is a mess right now. There's ejucovy/django-svenweb and socialplanning/django-svenweb .. ack, I'm filing these issues on the wrong one -- the canonical repository should be socialplanning/django-svenweb.

There are multiple branches ... the opencore branch is the primary active one, but it doesn't work unless you're in an opencore environment.

1. Issues need to be transferred to socialplanning/django-svenweb
2. The repo ejucovy/django-svenweb should be deleted
3. The master branch should probably be deleted (after a review of the diff) and the opencore branch should become master
4. The opencore branch needs to be refactored into a standalone/independent master branch, and an opencore-integration/wrapper package with a dependency on the master branch
