T. Joseph Carter 49fa865ec5 Add beta run-local support for development
This is similar to what's already done in A2SERVER, but there's both
more and less of it.  Fewer scripts run during the installation phase
(generally just setup), but there's a lot more tools and pieces that are
downloaded.

This is complicated somewhat by the single setup script making it hard
to work on just one piece at a time.  We'll begin addressing that soon.
