Lots of changes: Two binaries (selection/pw auth), qmake -> cmake, gitignore, more error handling

1. We now have two binaries: One pops up when the print job comes in so you can
select the printer, duplex, copies, etc... The other one pops up when used as
a backend and handles authentication by asking for username and password (WORK
IN PROGRESS!). This is to better handle things like smb printing

2. We use cmake everywhere, and now that we want two binaries it made sense to
switch.

3. Gitignore, well, what to say

4. Show an error message when calling ghostscript for grayscale conversion failed,
insted of just doing nothing and not even closing the GUI.

5. Keep the printergui open for a few seconds after printing, but hide the
window. Later we want to check in the password gui if the printergui is
open to make sure we really should run, and maybe even exchange some information.
