Add a studio FAQ / troubleshooting steps to SIS

[markspolakovs]

We often have different presenters having the same issue with the same fix, so it may be useful to have a FAQ somewhere in the studio with common troubleshooting steps.

Tempting to put it in SIS - that presupposes that presenters can open SIS and find the page though. But a paper version would go out of date quickly.

If we do decide to go down the SIS route, an implementation could be to use a news feed, similar to how the noticeboard works.
