Some projects reference caret Maven repositories and if they are down they slow the build

Some projects are still referencing the caret maven repos. They are currently down and its taking me ages to build Sakai with a clean repo. They are referencing RSF which has been migrated to the Sakai repo anyway so they are redundant and unnecessary.

All references to them should be removed.
