Subject: [PATCH] Adds new configurable option to shrink wrap list items using
 S2ChoiceConfig.shrinkWrap or
 SmartSelect.single/SmartSelect.multiple.choiceShrinkWrap. If choiceShrinkWrap
 is true choices list will shrink wrap the choices, causing the list to resize
 based on the number of available choices, by default it will shrink wrap
 which was the default behaviour before this change.
