Unhelpful hints about classes on frontend + whitespace issue

[koeaw]

Describe the bug
The model.__doc__ value we use to inject docstring information into the frontend, where it can be accessed via hover tooltips, is only useful for classes which actually have a docstring. For classes which don't, __doc__ seems to fall back onto the class definition.*

Additionally, the resulting <abbr> HTML tags seem to mess with whitespace: the class name may be preceded by a newline, though I'm not entirely sure if that is to do with the formatting and/or length of the docstring contents (which go into the "title" attribute of the <abbr> tag) or the way the tag is included (via templatetags).

Example:
Looking at the classes in the "Relations" menu, I see this issue with the "Property" class but not with "Triple" (neither of which currently has a docstring).

Screenshot:

*A cursory look at the Python docs suggests __doc__ is supposed to default to None when there is no docstring. The behaviour I'm seeing, however, mirrors that of inspect.getdoc().

Using the new generic base views, the class information is not displayed in the frontend anymore, therefore closing this
