Improvement: No Assessment Templates/Types

Since teachers keep missing out on the settings (ALL THE TIME) when making tests, i.e. making tests that are anonymous when they wanna be able to grade them, setting up timed tests that fails to save cause no time limit is set etc etc We decided to remove the possibility to not make your own settings. We removed preconfigured tests and quick creation button. Only thing left: Name a test and create it > Do your settings before publish. The fix is divided into three parts.

Changeset 636: Removed Quick-button
Changeset 679: Removed dropdown with predefined testtypes
Changeset 687: Removed testtypes from subnavigational levels
