moved saving logic from admin to model to make writing tests easier. Recreating an add action in admin interface is very cumbersome
reverted changed to admin as comicmodels.model.comicsite was taking on way to many responsibilities, in this case handling users and permissions. Models should only contain simple methods and members
small bugfix to make test creation of site work
Testing admin urls first version Needs refactoring. Testsite and pages are
now created as if they were created through admin interface, setting
correct permissions. Loggin in as admin is also working.
Re-enabled south migration for each test

Because errors were solved. This implicitly tests the migration from clean
install, and makes sure the test database is as up to date as possible without becoming stale, which would happen if we would not migrate, but use a snapshot of the database for testing.
Moved tests from comicmodels to comicsite.

The idea behind this is that comicmodels should be about the models by
themselves, while comicsite is about the integrated whole. Many of the
tests are about the integrated whole, for example testing download of a
file from a link generated by a template tag.
refactored tests to make test setup cleaner and more reusable
fixes #187 - COMICWebWorkstation will load again
Can now set server and port inside visualization template tag, for debugging
