Add assessment summary for collection. So now it also shows assessments
for its file groups.
Refactored how assessment table is shown a bit. So controllers which use
the view are responsible for setting up both the @assessable and @assessments.
Note that with the way STI and polymorpism interact we have to
set the assessable_type to the base class of FileGroup in the assessment -
the FileGroup subtypes won't work. Rails does this correctly (e.g.
when using 'create' or 'build'), but we need to be careful when
setting up the tests.
