Implement scratchpad

Implements the following commands:

* move scratchpad
* scratchpad show
* [criteria] scratchpad show

Also fixes these:

* Fix memory leak when executing command with criteria
(use `list_free(views)` instead of `free(views)`)
* Fix crash when running `move to` with no further arguments
