* The DB_UPDATE_VERSION will always be one greater than the last numbered script in this file.

* If you change the database schema, the following are required:
* 1. Update the file database.sql to match the new schema.
* 2. Update this file by adding a new function at the end with the number of the current DB_UPDATE_VERSION.
* This function should modify the current database schema and perform any other steps necessary
* to ensure that upgrade is silent and free from requiring interaction.
* 1. Update the file include/dbstructure.php to match the new schema.
* 2. If there is a need for a post procession, update this file by adding a new function at the end with the number of the current DB_UPDATE_VERSION.
* This function should perform some post procession steps but no database updates.
* 3. Increment the DB_UPDATE_VERSION in boot.php *AND* the UPDATE_VERSION in this file to match it
* 4. TEST the upgrade prior to checkin and filing a pull request.
