lib/sh/local.sh: database connection vars: connect to vegbiendev via ssh and run commands locally, to allow running commands as root (which can only connect to the database locally). this effectively requires an ssh account on vegbiendev, but any ssh account (including an anonymous one, if we set one up) will do. this causes schemas/VegCore/VegCore.my.sql, VegCore.pg.sql to change, because they are now created by mysqldump running on vegbiendev (Linux) instead of on a Mac.
