libnotify support about nougat

My take on this is that there's no really point to it when you can just append && notify-send to a command.

You can append notify-send, but that still gets sent even if you cancel nougat with escape.

So ideally we should have the exit code set to what the screenshot backend returns, if applicable.

If you could test the backend that you're using with command && notify-send 'test' then hit escape and tell me if it sent the notification, that'd be great. No big deal if you can't, I'll test it later today in that case.

If you use maim or scrot, then the command should be easy enough (maim or scrot). ImageMagick can be tested with import -window root.

Running maim -s > test.png && notify-send "test" and hitting ESC doesn't send a notification.

Just what I needed, thank you.

Now it's just down to whether nougat should simply return the same exit code, or if there should be a post-command variable.

Post-command variable clutters the configuration (more), and would make the code slightly more complex. The same exit code would mean that a user could execute any command if nougat succeeds in taking a screenshot, but means users would have to constantly type the same thing over and over again (in the case of notifications).

Could do both, too. Which I'll likely end up doing.

Should be good now, let me know.

Yep! Now I can do nougat && notify-send "Success" and have it send notification when i make a screenshot, and no notification when I cancel with ESC!

Thanks!
