Player quit command crashes trogdor-server

Client side:

COMMAND james
GET
quit
Connection closed by foreign host.

Server side:

Segmentation fault (core dumped)

Hmmm...

This was because if I'd executed a quit command, the player was removed from the game (deleted), afterwhich I was attempting to access its members to reset its input and output streams. You can guess what happened after.

Solution was to check if the player still exists before resetting its stream objects.
