Slot List Panel (e.g. Find Inputs Dlg): Fixed Unit Type Sorting
Bug Number: none
Release notes (y/n): y
For Release Nums: 6.3

Fix to Slot List Panel sorting order for Unit Type and Timestep 
Size Columns.  This panel is used in the following dialogs:

  (1) Find Slots with Inputs
  (2) SCT: several tabs

Also, added minor utility function to Sim/SlotGUIUtils:
  bool singleScaledUnit (const QList<Slot*>&);
