* feat(StatusChatListAndCategories): add drag and drop support for categories
This adds support for dragging and dropping chat list categories.
To persist reorder of chat categories, the new `onChatListCategoryReordered`
signal can be leveraged.
Drag and drop of categories is turned off by default and needs to
be turned on using `draggableCategories: true`.
Closes#227
