MDL-50794 workshop: Allow restricting submitted file types
It was reported at the Open University that there have been some
problems with the formats of files submitted by students. Not all
students completed their outlines as a Word .doc (despite this being the
format of the template provided). Some formats (e.g. .pages) couldn’t be
translated by some of the reviewing students. Therefore, they were
unable to provide a review and the submitting students not receiving any
comments.

This patch allows the teacher to define list of allowed file types that
can be attached to submitted work and/or overall feedback in the
workshop.
