Subject: Added tools/boca-createdb.sh

This script contains commands to create a DB to a locally installed
postgresql.

If DB is running in another host, this script updates
$bocadir/src/private/conf.php file.

Also if this script is executed in a configured environment it prompts the
user to clean current DB.
