Update location of scala-tools jars
Add eclipse files
Make h2 the default, and make it work

Running into autocommit on problems with SQLite.  Could the be the brave
library, not sure.  Using H2 doesn't appear to have these issues, but
the SQL needed to be cleaned up.  Not sure I got them all, but commiting
for now.  Could probably use some test cases.

Also add a bin/h2-client script to view the database, which helps me
attempt to understand what is going on.
