Can't swap cards between rank lists

[matt-dray]

You can set sortable_options to have swap = TRUE for each list so that cards replace each other within a list and between lists.

I think swapping is the more expected behaviour when moving cards between rank-lists. I think sorting is best within a list. However, we can only have all swapping or no swapping.

Without swapping, you can't move any cards if the pool and hand are both full.

However, the app starts with an empty hand, so you can't swap anything with the pool. Can swap be overidden if there's nothing to swap with? Could an 'invisible' card be used as a dummy and destroyed when swapped? I think this gets more into the JavaScript space.
