Changes

** start selected installers with GUI (some installers break if not started with a GUI) - seems to be very complicated, and wpkg.js was already started in the background

* testing setting: providing "user" for a network path doesn't work; one needs to add DOMAIN\user or WORKGROUP\user. "Test" button will say that the settings are correct even when we don't specify DOMAIN\ or WORKGROUP\ though.
