Resolve merge
Merge remote-tracking branch 'origin/master'
Removed more underscores from get_card_from_zone
Updates to client, added different interface

client.py got some fixes to quit when you say 'n' and to start
asking questions when the game starts. It still doesn't do anything

Added cmd_loop.py and clienthooks.py which use the cmd module to
start an interpreter. Haven't gotten very far, but there's some
description in README.md.
