Added specific code to FirstRun.UUpdateIni to delete detail pane tab index entry from config file. Modified TFirstRun.UpdateCfgFile to call the new code instead of deleting key explicitly, and to do it for config file v8 as well as earlier.
Changed TFirstRun.UpdateCfgFile to update code generation config settings re renamed key. This uses new UpdateCodeGenEntries routine in FirstRun.UUpdateIni.
Updated config file version to v9.
Other minor supporting changes.
