Setting preset 4 brings up a dialog with the name of preset 1

[lrucker1]

          QString presetText = QInputDialog::getText(nullptr, tr("PTZOptics"),
                                                 tr("Preset #4 Name:"), QLineEdit::Normal,
                                                ui->mem1->text(), &ok);

That "mem1->text()" should be "mem4->text()". This has been annoying us for a while.
