Mr-DaveDev fbb3c2e022 Limit parameters available on webcontrol (#530) 
Implement a new configuration option which allows users to specify the
type of parameters which can be accessed via the webcontrol page.  The
new option permits levels 0(none) to 3(restricted) with a default of
none.  This option is to enhance the security associated with the
application for users that may expose the webcontrol port publicly.
