Simple way for screen locking written in haskell

It's my first haskell programm. I forked the c code i took as a reference.

Dependencies

• Unixutils-shadow (1.0.0)
• base (4.12.0.0)
• unix (2.7.2.2)
• split (0.2.3.3)
• X11 (1.9)

TODO:

• Don't use setuid. Find something more appropriate to get the shadow entries (maybe pam?)
• The hash should be fetched when the user tries to unlock the screen and should be overwritten 'till the next request, so the hashed password can't be read from memory
• implement xkbcommon to let keys through like VolUp and stuff.
• Creating black windows for every screen or let all screens fade to black (I want nothing too fancy)

BUGS:

• Works perfectly fine when i start it in my terminal emulator (gnome-terminal) but if i start it via a shortcut in a gnome-session, weird stuff happens... I have to investigate.
