[BracketsAdder] Regex missing some cases

[Arthoni]

Missed cases:

• if (ui->BackwardRadioButton->isChecked()) \n Options |= QTextDocument::FindBackward;
  (because of | in block, 4 times)

• for blocks
  (Example: for (WareFileEditor* Editor : m_WareFilesByPath.values())\n Editor->updateSettings();, 5 times)
