LibCards: Support non-alternating colour patience games

Browse source 
This introduces a new MovementType concept to LibCards, starting the
process to allow other patience games to be implemented using it - that
differ more substantially from Klondike in logic.

This is currently used for two purposes: 1. to verify that the
'grabbed' stack of cards is valid* (sequential and correct colours) and
2. to allow 'grabbed' stacks to be pushed onto same-colour,
either-colour, or alternating-colour stacks

* Klondike doesn't need this logic, as per how the game works any
  'grabbed' selection is guaranteed to be valid.
