Description

What?

This builds on pull request #1275 , and is made against the 1.20 branch. In other words, #1275 should be checked first.

I ended up doing a dedicated _siblings.html template for LTI tool, because the logic is slightly different than in the original one (this supports also the case where LTI is limited to a single module, in which case it will not be possible to navigate to Course content TOC or other modules.)
