Migrating more signal/slot to the new member pointer system. Unlike the earlier signal-side overload fixes (QComboBox/QSpinBox

Browse Source 
etc.), these three are ambiguous on the *slot* side:
activateProject(QETProject*)/activateProject(ProjectView*),
closeProject(ProjectView*)/closeProject(QETProject*), and
showError(const QETResult&)/showError(const QString&) each have two declarations on QETDiagramEditor. &QETDiagramEditor::activateProject
etc. alone won't compile with two candidates present; qOverload<T>() picks the one matching the actual signal's argument type, same as
the old SIGNAL()/SLOT() macro text did implicitly.
