Fix minor issues with the Setup Show Form in Scheduler including issue with re-arranging of shows from reverting back when changing Tabs and issue with the Cancel button not working correctly.
Implemented Drag and Drop for sequences in show list and removed the manual up/down arrows.
Improved the Remove buttons process. When removing a sequence from the list the previous sequence in the list will now be highlighted. Saves going back to select another sequence to highlight. Seams like a natural way for it to work.
