Added student proposal review page.
The proposals can now receive a score. Only org admins can assign a mentor. Every mentor can state if he wants to be a possible mentor (or be taken of this list).
TODO's have been added for the access check, comment system and autocomplete.

Coverage: code coverage testing for Python
Coverage.py is a Python module that measures code coverage during test execution.
It uses the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
