Windows: Allow system encrypted devices to be mounted from WindowsPE - even if changing the keyboard layout failed (#539)

Browse Source 
When my system broke and I had to use WindowsPE to rescue some files the password dialog always closed immediately. There was no chance to mount the system device using the GUI. It took me a while to realize that I could try using the CLI by passing the password as a parameter (which might not be so obvious for not advanced users).
