Now we're using `setUpTestData` more, not running some slow code,
using MD5 hashes for speed, and using bulk_create.

Also removes some dead code.

Wolktm can't be deprecated because Django doesn't do longpolling

Partially implements #101

Notable TODO is adding messages for end-users on actions

This setting defaults to 1000, but when we want to perform
actions on more than 1000 entries in the admin, this fails.
This is useful when e.g. modifying/deleting all member records,
and 10K is still easily sufficient to protect against DoS.

This is required when we use the sites middleware

This is incomplete as events etc are not implemented yet, but should suffice as a decent starting point

Closes #27, but we should track this for new apps

* Models and admin page for events
* Add organisers to events
* event overview page for organisers

Output is cleaned with `bleach` in the frontend
