f2145ce867 mw8080bw: multiple improvements to gunfight netlist audio 
Model for transistors adjusted, replacing default NPN transistor
model with a high-gain NPN transistor type that more closely
resembles those used by the real Gun Fight sound circuits. This
has a quite obvious effect on the shot sounds, and it seems the
circuits were designed for this effect.

Made all volume potentiometers user-adjustable; previously fixed
at 50%.

Replaced abstract model of noise generator with component-level
one, including a model of the generator's zener diode. Zener
noise is provided by an associated Gaussian white noise source
running off a 48 kHz clock. Both the zener diode and Gaussian
white noise source are component models recently added to the
netlist library.

Supply voltage to amplifying transistors tweaked downward from
16.5 volts to 16 volts, determined by properly analyzing power
supply circuit and confirmed with a documented reference.

Much more commentary describing the sound circuits' function and
modeling issues.

735752cea8 netlist: reduce overshoot impact on NE555 astable frequency. 
If TRIG and TRESH are connected overshoot compensation will be enabled.
The approach is raw but delivers results (at 5 to 10 steps per
discharge/charge) within a couple of percent. Please take into account
that any datasheet formulas are idealistic. Neither capacitor, resistor,
internal resistor tolerances are taken into account. Nor are ambient
temperature and chip temperature.
