Add project-wide search & replace to the scripting API

Browse Source 
qet.searchAndReplace(kind, field, pattern, replacement, useRegex,
caseSensitive) finds and replaces a substring or regular expression
within one text field across every folio, as a single undo step --
kind is element_info, conductor or text. Unlike a script loop over
elementInfo()/setElementInfo() (or the conductor/text equivalents)
doing the same thing one item at a time, each pushing its own undo
entry, this wraps the whole run in one macro.

This is deliberately NOT a wrapper around QET's own "Search and
replace" panel (SearchAndReplaceWorker): that one is a batch
overwrite-with-sentinel template built for picking items from an
interactive tree, a poor fit for a script that can already say
precisely which items it means. This does what the name plainly says
instead -- an actual substring/regex replace within each item's
current value.

Found and fixed while writing the first conductor-kind test: a hub
topology (several conductors sharing one terminal, e.g. a star wiring)
made the conductor branch pick terminal1 unconditionally to address a
Conductor object through setConductorProperty() -- for a hub member
conductor, terminal1 is the shared, ambiguous hub terminal itself
(findConductor() correctly refuses to address a conductor through a
terminal carrying more than one), so every conductor touching that hub
silently failed to update, returning a changed count of 0 with no error
for a genuinely matching project. Fixed by preferring whichever of
terminal1/terminal2 carries exactly that one conductor.

Also caught during testing: an empty macro (a run that matches
nothing) still gets pushed onto the undo stack by QUndoStack::endMacro()
-- it is not silently discarded the way the earlier revision assumed --
leaving a confusing no-op "Rechercher et remplacer" undo entry. Fixed
by counting matches in a dry run first and never touching the undo
stack at all when that count is zero.

textContent() is a new small getter alongside the existing
setTextContent(), filling a gap this needed (reading an independent
text's current content) that is independently useful too.
