This patch keeps the screen unlocked but keeps the input locked.
That is, the screen is not affected by slock, but users will not
be able to interact with the X session unless they enter the correct
password.
Unlike the "Unlock Screen" patch, this uses an arg (-u) to enable the
unlocked screen functionality, and the mouse will remain hidden. The
primary use case for this would be in a script to spawn a screensaver
when the screen is locked. AFAIK the existing arg parsing system does
not support continuing execution if a flag is set, so sorry for the
messy arg handling.
