Fixed: notification xib converted wasn't displayed anymore

Previously, the notification xib converted didn't show up. Now it does again.

This PR fixes another issue. Now when checking the the compilation issues, we only pass objj file to the command objj.
Fixed: include path doesn't take the absolute path
FIXED: config warning issues
NEW: option to define if the reporting window should stay on top
Fixed: warnings from objj were displayed several times
