allow typing in password immediately instead of waiting for fingerprint scan to timeout.
If you follow https://wiki.debian.org/SecurityManagement/fingerprint%20authentication you get fingerprint authentication on the lock screen.
However, if the lock screen is waiting to scan a fingerprint, you can't type in your password until the fingerprint scanning times out. You should be able to do either one at the same time. I think this is going to have to be fixed as part of #145 .
