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).

QHash/QMap::keys() allocates a list of every key on each call, then
contains() searches it linearly - an accidental O(n) plus allocation
where a direct O(1) lookup was meant. 35 occurrences across 7 files,
found while profiling project load times (context: #553/#560).
The hot one is ElementPictureFactory::getPictures(), which runs once
per element instance on project load: on the 3399 KiB example project
(191 instances, 129 cache hits) the keys() detour cost 45 ms of the
1.34 s total - measured, not estimated; the fix reproducibly shaves
~35-45 ms off that load. The remaining call sites are UI paths
(search&replace, dynamic text model, undo commands) where the waste
scales with selection/model size.
No behavior change: for QHash/QMap, keys().contains(k) and
contains(k) are equivalent by definition.

In case of user try to delete a terminal element who is bridged
or belong to a physical terminal with more than one level, the deletion
is aborted to avoid mistake in the terminal strip parent of the terminal
element. A dialog is opened when the deletion can't be to explain to
user what to do for enable the deletion.

semantics. You get more than 50 Qt related compiler warnings, ranging
from unneeded memory allocations to misusage of API, including fix-its
for automatic refactoring.

This commit fix it : When element is removed one or several conductors are created (if needed) to conserve the electrical potential.
