ds script assumes sandbox environment

[mshmsh5000]

If the ds script is to work outside of sandbox instances, we need to provide for variations in MySQL connection strings. So two immediate places to address:

Initial DB catalog creation

drush site-install

I imagine the best approach to this will be env vars, a la this approach.

I believe this is addressed with this: #860. Safe to close?
