[Mac] white tray icon on dark scheme

From the betatesting http://forum.arduino.cc/index.php?topic=363469.0

The second issue was that I couldn't see that the Agent was running. My system is set to use the Dark menu bar and Dock - the ArduinoCreateAgent.app does not show an icon on the main display with the Dark menu, it does show on the non-active display menu, so I finally figured out that it was running, and the Agent took me to the http:// pages.

Also the grey icon on Mac is really pixelated, here an updated one https://drive.google.com/a/arduino.cc/file/d/0B7BGUDKhgaDgRWo4ZkNPU2kzcW8/view?usp=sharing

@facchinm I know this is not a blocking issue but quite a few people are reporting it :)
Any way we can help you?
