Report generator ng

Description

Refactors the assignment to contain sane metric settings objects, but this required a full system refactoring but I was in too deep so deal with it.

Also fixes the report generator to use these new settings objects.

Changes

• The assignment no longer depends on the magic options hash map
• A new report generator
• The old mongo script executor now implements the SRF
• Scripts can now return a grade, which can count towards the final grade in ways still to be implemented
• Analyzers now return their metric names as part of the enum instead of a magic string
• Stupid analyzers have been fixed and await death
• Fixed logging being broken in the worker due to CK forcing log4j upon the worker

Additions

• A plugin framework for SRF
• Extra logging during boot and nice art

Test and Review

Started off as #147 (closed). Got out of hand and now also resolves #161 (closed). The new entity system and the associated reports also resolve #139 (closed). Made #148 (closed) only worse on the old UI for some reason but that should not matter.
