Subject: [PATCH] Config: Create config directory if it was deleted while
 runtime

In few previous commit a fix for incorrect directory if tool was
installed by dpkg was added, now this patch adds on top of that - if
users have deleted files, we probably don't want to screw their
directory wherever they ran D1GraphicsTool in by saving config file upon
closing the app here, so it creates the path once again and writes
config here.
