cheekyms: add preliminary netlist sound based on schematics provided by Sam Grech

Browse Source 
(nw) It doesn't work quite right yet.  The "Hammer" and "Pest" sounds
are generated by free-running 555/556 timers and gated with LM324
applifiers.  For whatever reason, the netlist system produces a kind of
buzzing from the "Hammer" circuit when it's supposed to be suppressed,
and it doesn't think the pest sound should be suppressed completely so
you can always hear it at a low level in the background.  The "Cheese"
circuit is a bit weird - either they're using the base-emitter junction
of a 2SC945 as a signal diode, or there's an error in the schematic
(collector is shown unconnected).  Connecting this part of the circuit
causes the netlist system to hang, so R2/R3/C8/Q2 are not connected for
now.
