1) Added new field to the organiser model called charge_tax. Added the migration for this.
2) Renamed tax fields columns in the database to be the same as the other organiser fields for consistency.
3) Added charge_tax option to the various organiser create and edit pages.
4) Have re-enabled some tests and used the @group passing label so we can start running tests for the various parts of the applicaiton.
