DropTrash

### DropTrash 2022.7.0

- Updated to WotLK, and moved all 3 versions under the same addon name. The old
addon dummy still exists called "DropTrashTBC" just for the sake of automatic data
reimport. It is safe to delete it after one start of the game.
- New window for deleting and adding items, to replace old buggy scroll box.

Remember you can hide the floating button in options and can bind keys to show the window and to remove the trash.
