Discussion #1158, stacked on the limit itself. Two of QElectroTech's own
tools wire several terminals as a star, every terminal to one of them:
"create wires in a drawn polygon" (also qet.addConductor()), and deleting
a symbol, which rewires the far ends to keep the potential. Six terminals
give the hub five wires, which the project's limit forbids.
When the project sets a limit (and the master switch is on), both now
wire the terminals one after another instead, from the top left one to
the nearest not yet wired (WiringRules::chainOrder()). The polygon tool
also skips a wire whose terminal is already full. Without a limit, both
build the star as before.
tst_wiringrules: the chain order, and through the real binary that
deleting a symbol wired to four others leaves them with at most two
wires each under a limit, three on one of them without (checked to fail
with chaining turned off).

Discussion #1158: a real terminal takes one or two wires (four with
double ferrules), a folio report is a virtual point that carries one, but
QElectroTech lets any number of wires be connected anywhere.
Project properties > General gets a "Conducteurs par borne" group:
- the most wires a terminal may take (0, the default, is no limit);
- "one wire per folio report".
When set, a new wire that would go past the limit is refused: the
terminal shows red while dragging, as for any refused link, and a tooltip
says why on release. Auto-connect on placing, moving or multi-pasting a
symbol skips full terminals, and qet.addConductor() refuses with its own
message. Wires already drawn, opening, pasting and undo are never
refused.
Settings > General gets a master switch, on by default, that turns every
rule of this feature off in every project; the project group is greyed
with a note while it is off.
The rules live in wiringrules.cpp. The project setting is saved as
<wiring_rules .../> only when a rule is on, so a project that never used
it saves exactly as before; an older version drops it, which means "off".
tst_wiringrules covers the rules, the save round trip and, through the
real binary, that a wire past the limit is refused unless the master
switch is off (checked to fail with the limit check removed).
