UI Overhaul

- You can now Drag-Drop re-order operations
- The delete buttons are now on the operations themselves
- These two together mean that you now dont have to (and cant) select operations anymore
- Added ability to view the path on a filename in the before- and after-lists
- Also updated Avalonia to preview8
