Indentation fix (pylint).
admin_manager.py whitespace cleanup (pylint).
channel.py whitespace cleanup (pylint).
channel_manager.py cleanup (pylint).

This one actually includes an import "fix" (explicitness), so it's
not just whitespace.
chat.py pylint fixes.
configurator.py pylint fixes.
die_roller.py pylint cleanup.
game_master.py pylint cleanup.
location.py pylint cleanup.
login.py pylint cleanup.

This actually caught an unused import.  Woot.
player.py pylint cleanup.

This caught an actual bug, in that the state variable that can be
passed into a player creation (which isn't currently used, but...)
wasn't being used to initialize the player's starting state.  Oops.
server.py pylint cleanup.

A lot of changes here due to needing to get rid of relative imports
and realizing that everything's an object nowadays.  This /was/
the second source file, though :)
utils.py pylint cleanup.
four_player_card_game_layout.py pylint fix.
game.py pylint cleanup.
goban.py pylint cleanup.

Caught an actual, would-cause-a-crash bug in one function, plus it
reminded me to axe a FIXME, since I /am/ using a more efficient
bit-based representation (namely bitstring).
hand.py pylint cleanup.
piece.py pylint cleanup.
playing_card.py pylint fixes.
seat.py pylint cleanup.
