Deployment work.

* Added automatic creation of JDBC resource and connection pool
* Created "init.sql" with the desired initial database state
* Changed persistence.xml table generation strategy to "None" since init.sql now sets up the DB

Nobody needs to run "test" *after* deploying now. Just make sure you have a db named "opensale_dev" with a user named "opensale" password "opensale" who can (create/alter/drop) table and insert/select/update/delete on that database.
