Subject: [PATCH] Added wmud_client_send() and a client state field.

* The wmudCLient struct now has a state field, which indicates the current
  state of the client (we are waiting her to log in, or to enter a command,
  etc.)
* Created the wmud_client_send() function to send formatted strings to a client
