Add Up/Down buttons to the compositions docker
This adds up and down buttons to the compositions docker, giving the user the ability to reorder their compositions after creating them.
Test Plan
Create three compositions:
- Check item can be moved up
- Check item can be moved down
- Check top item cannot be moved up
- Check bottom item cannot be moved down
- Check contents of the compositions are consistent after reordering
