Qt4 Port: Scenario Manager Dialog Slot List (Qt3 List Still In)
Bug Number: none
Release notes (y/n):  no
For Release Nums: 6.3 

See some screenshots:

The old Qt3 list is shown on top, and will be removed on the next
commit.

Some differences:

(1) Multiple Slot Item selection, which is supported by most 
    operations. (The Qt3 version supported only single-item 
    selection).
(2) Optional Column and Sorting Controls.
(3) Custom Order (one sort option) is now global for the whole
    model (can be applied within any of the Scenarios).
(4) Showing SimObj Type Icon and -- if any Account slots are 
    represented -- Account Type Icon.
