Updated zpanel_core.sql installation SQL script to default the 'debug_mode' value to 'prod' instead of what is currently set to 'dev' this resolves issues that may occur such as the one documented in bug #695:- http://bugs.zpanelcp.com/view.php?id=695
Adding update script SQL to set the default values too as the the previous commit, this forces ZPanel installations to disable PHP error reporting by default (not sure why it was previously set to 'dev') this will disable outputting of exceptions by default.
