Add IPC:

  Manaplus now accepts connections on the 44007 port.

  * Uses SDL_Net/SDL_Thread.
  * Port can be changed with envvar IPC_PORT.
  * Default port is first checked then incremented until one is available.
  * start on demand with /ipctoggle (shuts down server socket)

  It has a simple text protocol: TYPE arg1 [args]...
  Message types:
   * CMD: execs a command supported by manaplus, e.g /emote
   * LTALK: talks in general tab
   * TALK: talks in current focused tab
   * [TODO] KEY: do as if the KEY was pressed on keyboard
