LDEV-1914, LDEV-2160 Set minimum values for grouping steppers in PI. Fixed disabled stepper problem. Fixed up some of the code in the PI, specifically explicitly setting null values to properties of the grouping object that do not apply to the chosen type of grouping. This fixed some persistent values when switching between group types.
LDEV-2140 Added support for tool output definition information to be received from flash when tool activity is created, and also fixed up some i18n stuff
LDEV-2140 Progress toward flash export to gradebook support. Added label & combobox to pi, populated it with toolOutputDefinition types for selected tool act. Got copy/paste copying selected definition working also
LDEV-2117 Fixed support activity button being enabled in live edit if support activity already on canvas, fixed support activity button being disabled in normal author when after new button is clicked and the canvas cleared
LDEV-2117 Support activity container now set to read only in live edit if one of the child activities has been attempted to prevent deletion of parent container after child has been attempted. Also fixed compile error involving ObjState class
LDEV-2117 Fixed message when user tries to add a non tool/parrallel act to the support act.. it now properly refers the activity type they tried to add
