Add an option to specify the location of the save file and check already saved credentials

[opteh]

This is a very interesting utility.
I would like to ask the developer to add an option to specify where to save the password file.
We suggest adding fakelogonscreen to everyone's autostart.

Also the option to check already saved credentials would be very useful. And if the user credentials are already saved and they are correct, then fakelogonscreen does not display the fake logon window.
Thanks!
