TEST PLAN
  Clicking the "add widgets" button multiple times in widget explorer no longer crashes/confuses it because the Repeater destroys its items when model is assigned a new JS Array as is done in widget explorer.
  
  Also the category selection in widget explorer still works.
  
  There's no addMenuItemAt method and the old code also didn't care about the order of items so it shouldn't be worse than before.

REPOSITORY
  R242 Plasma Framework (Library)
