Trying to merge stash where crud migrated to external app.
Move crud into its own submodule/app.  Error with Auth/PortcullisUser.

The PortcullisUser needs to be migrated to use the custom user from django 1.5.
Merge branch 'development' into jdev
Delete slickGrid submodule.
Use new crud github repo "chucho"
Change to work with chucho repository.
Convert code to use generic auth user.
Add migrations and finish migrating to PortcullisUser1
Add stream subtree back to project.

I was accidentally removed when crud was moved into chucho.
Update chucho to version using col.app.
Merge branch 'development' into jdev
Rename PortcullisUser1 to PortcullisUser.
Merge branch 'development' into jdev
Add auth models to this migration for backing out of migration 0007.
Remove the auth_user tables.
Merge branch 'development' of github.com:visgence/portcullis into development
