Another temporary script. This performs the tasks from ivan.sh related
to installCommTools. It differs from that block (which has not yet been
formally replaced) primarily by having a rewritten and hopefully more
logical installation for oysttyer.
Oysttyer probably should be broken into its own script—all of these
things should be really—but this one in particular because it's so
involved even compared to other installations because we have stuff we
need to clean up first.
