Handle CTAT 1.1 instances

[darrensiegel]

The Intro to Stats course contains CTAT activity instances that the digest tool does not handle correctly. While the digest tool will successfully convert the course and create a digest, the ingest in Torus fails during the Oli.Ingest.RewireLinks.rewire/3 step due to the missing CTAT resource.

The course SVN branch is: https://svn.oli.cmu.edu/svn/content/statistics/statistics/trunk.

I believe I've found the instances of these activities in the course content by running:

$ find . -type f -name "*.xml" -exec grep -H "cmu-ctat-tutor_1.1.dtd " {} \; | cut -d":" -f1

Which yields:

There might be some additional resources beyond those xml files. I believe there might also be some image and text files that go along with that content, at least it did years ago when originally authored.
