New improvements to my tmux configuration.

  * <prefix> S to create new named (with prompt) session.
  * Disabled mouse because it breaks gpm-like behaviour in terminal.
  * New bin/tml shortcut-script (like my old loved scl for screen).
  * Added "deprecated" comment to scl home window title.
    ...time for tmux!!! :-)
