jerrrrycho b5953ef61e feat: lock the field shunting in both directions on resistive positions ...

With ScndCtrlResistiveLock=Yes the shunt controller can't be moved down
either while the master controller is at zero or on a resistive position
(eu07/maszyna#402: "inc/dec").

So that a shunt step can't be left stuck there, the shunt controller drops
to 0 whenever the master controller is at zero or on a resistive position:
right after IncMainCtrl()/DecMainCtrl() move it there (before the
positions go down the consist) and in every update, for the master
controller set directly (AI clamp, consist). Electrically nothing changes,
the relays already drop the shunting on resistive positions. Reducing
power is never blocked: the EP09/ET21 master controller turns back with
the shunt on, the ET22 keeps its interlock (shunt off first), and on the
ET22 a shunt left on at a resistive position would otherwise lock both
controllers.

Tests: the shunt goes down on resistance-free positions only; the master
controller taken back or up onto a resistive position from a shunt step,
by hand and directly, on the ET22 and EP09.
