Title: [osx/windowing] - add "Window Server" to the whitelist of obscuring

windows.

As the title says - just another one for the list (spotted in a log file from a user). Window Server is an osx internal service and shouldn't even be treated as a real window if you ask me. But seems since mavericks - everything is possible ;)
