Gnats 5190: Slot Name format setting not working in (Excel) MRM Config

Changes to the 'Slot Names' QComboBox (with three possible values: 'Index',
'Short', 'Full') were not having an effect -- the widget would just revert
to its prior value next time it was updated.

This was due to a missing Qt signal/slot connection for the QComboBox,
_excelNameComboBox; slot method: MultiRunEditDlg::excelNameOptHandler.

Signal/slot connections for this dialog are defined in the Qt4 Designer
UI file: QtRun/MultiRunEditWidgets.ui.

This is being fixed for RiverWare patch 6.1.6 and 6.2 (development).
