make_event() lowercased the event name twice: cParser::getToken() already
folds ASCII via toLowerChar() (which intentionally leaves bytes >= 0x80
alone), then ToLower() ran std::tolower() over every byte on top of that.
With a non-"C" global locale, that second pass remaps cp1250 uppercase
accented letters (e.g. 0xAF -> 0xBF). Every lookup path - TTrack::AssignEvents(),
child-event resolution in multi_event, event-launcher name resolution -
normalizes only through the parser, so a registered name containing such a
letter can no longer be found: the track logs "can't find assigned event"
and the binding is silently dropped.
Removing the extra ToLower() makes the registration key match every lookup
site (ASCII-only folding, non-ASCII bytes compared verbatim), and matches
the direction toLowerChar()'s own comment already points at for UTF-8.
A whois with no triggering vehicle previously just wrote nothing to
the target cell with no trace in the log, which is a real pain to
diagnose from the scenery side (this is exactly the kind of thing that
cost real debugging time on a station script recently).

whois_event::run_() dereferenced m_activator unconditionally in every
branch (this predates this PR). getvalues_event::run_() and
putvalues_event::run_() already guard the same way elsewhere in this
file; whois_event was missing it. Single early return covers every
branch, old and new.
The +8/+16/+24/+32/+40 (and the new +48) modes all pick the reporting
vehicle the same way: the activator's own Mechanik if it's the primary
driver, otherwise the consist's controlling vehicle (ctOwner) - so the
event still resolves correctly if a wagon happens to trigger it ahead
of its locomotive.
+0 (train name / stations left / stop flag) predates that pattern and
never got it: it required m_activator->Mechanik directly and silently
wrote nothing otherwise. A whois hook placed where the loco doesn't
necessarily lead (e.g. a train that reverses direction, or one being
propelled) can have a wagon trigger the event first and the memcell
stays empty, with no error - hard to diagnose from scenery side.
Same owner-selection, same guard semantics (still nothing written if
neither the activator nor its consist has a controller), only the
source of the vehicle it reads from is widened.
When the Autorewident function is enabled, the EP fuse switch will no longer automatically engage or disengage if the player is controlling the train. This would happen for example when approaching a station.
