The Elf's master controller (EIMCtrlType 2) gets an optional emergency
brake position below its position 0, turned on by the new .fiz key
EIMCtrlMainEmergency=Yes in Cntrl (default No, no change without it).
With it the old positions move up by one (MCPN 5, neutral at 4): the
emergency position brakes fully at once and vents the brake pipe, like
the alarm chain or the Impuls's EIMCtrlEmergency. The loader raises a
too small MCPN to 5 and logs it. The Elf code with hard-coded positions
(CheckEIMIC, the MED full braking, the AI) takes the shift into account.
SVN data to change afterwards (dynamic/pkp/elf_v1, needs this exe):
- every .fiz with EIMCtrlType=2: EIMCtrlMainEmergency=Yes, MCPN=5,
DirChangeMaxPos=4 where present;
- the cab .mmd mainctrl entries: offset one notch lower (-0.06 -> -0.09),
sounds shifted one index up, new sound0 with
26284_elf_nastawnik_nagle_*.wav.
