-igs/igs_m027xa.xpp: Fixed inputs for Crazy Bugs (V103JP).

* The hopper is hooked up because an input for it appears in the I/O
  test, however both the Payout and Ticket buttons seem to use the
  ticker dispenser to pay out credits.

-machine/sc16is741.cpp: Implemented CTS/RTS deasserted interrupt.

-bus/spectrum/musicmachine.cpp: Get device out of global namespace,
 and some cleanup.

-lnux4004.xml: Include Linux distro in software item description.
