Make day visibility selectable on a tripos

[ieb]

The orriginal requirement was to make thursday through to saturday visible for a tripos. Presumably all other days are invisible. I can imagine that this will soon need to be a set of days.

There is a second requirement in this area that might be the same but also could be different.

Implement a flag that tells us whether the Student view should include/display Sat lectures for this Faculty.
Change Student view to act on this.

Should Faculty really be Tripos ? Is this actually the same thing as this issue or a separate requirement ?
