Completely revamp how PCDM uses the previous login information. Now you no longer need to specify which desktop to auto-login to if you have auto-login selected. It will first try to check for previous login information for that user, then fall back on the last login for the system in order to try and auto login. Also fix the PCDMd script a bit so that autologins work properly when triggered.
