BUGFIX: Added die() on Deny() in main Joyst_Model#Index() function to prevent Joyst from passing into the default controller function
Added experimental support for json-import data type which imports a JSON object into the row - allowing for NoSQL style row storage
Added access trigger which fires before push/pull
BUGFIX: JSON-Import type now correcly converted to a string before database save
Added ResetQuery() function to force CI to drop any half-finished query strings
BUGFIX: joystError is now always available - not just when an error occurs
BUGFIX: The new ResetQuery() function fires on every new query - prevents DB clauses in triggers that never fire from conflicting with later queries
