Crapette: a craftier AI (reserve-first, loads you, rearranges houses)

* cg-crapette.el (cg-crap--ai-unload-move): scored move choice preferring
new priority chain; raise the loop guard.  Update the commentary.
* test/card-games-tests.el: add cgt-crap-ai-enabling, cgt-crap-ai-loads-you.
* NEWS: note the smarter opponent.
