[Building Sakai] lessons for 10.3

[Hedrick Charles]

Some sites might want to look at using 10.x for lessons rather than the 10.3 tag. the direct URL button doesn’t work. It didn’t work in 10.2 either, so this isn’t a regression exactly, but it fails more visibly.

You can see what differs between the two by looking for the 10.4 tag for the Lessons project in Jira.

Part of the problem was trying to support both the way the direct link worked in 2.9 and 10. It now works as in 10 even when running in 2.9.
