Entering annotations are broken

[weiju]

Annotations don't work, there must be a problem in the whole process since the errors
date back to October 2016.

The problem is that this also causes the system to break in the analyze view

Ok, it seems that there is more going on here:
This is simply sloppy execution: Instead of storing annotations in its respective table and retrieving the possible values there, it is hardcoded in annotation.js.

The annotation table itself is empty. I So the system_annotations.annotation_id is actually not a foreign key, but conceptually a table of references to hardcoded values that only exist in a Javascript file with its description conceptually stored/hardcoded in sys_annotations.html.

This is wrong on all levels, luckily we haven't used the annotations system much so far. I suggest we entirely redesign and rewrite the annotations part instead of trying to fix it.

After thinking a while about this I will create a dedicated service with an API to track changes and this project will only serve as its user interface. This is also a pilot for moving the social and the measurement system into dedicated services.
