[wix-users] Uninstall the installer in CLI NON-silent mode show windows default UI

[Jürgen Schäpker]

msiexec /i <path_to_msi>

will show the MaintenanceWelcomeDlg if (Installed AND NOT RESUME AND NOT 
Preselected AND NOT PATCH).

When you customize the UI you could modfiy the maintenance dialogs and 
e.g. remove other buttons and only show the removebutton for uninstall - 
see src\ext\UIExtension\wixlib\MaintenanceTypeDlg.wxs.
