TrayIcon hides in Windows 7
Bug description
Windows 7 has the feature that unused trayicons get hidden to avoid the appearance of too many trayicons. In the windows options I can prevent specific trayicons from hiding but with Gajim windows forgets it after a reboot (or maybe after some time without reboot, i will focus that point).
Steps to reproduce
Just start Gajim on Windows 7 and wait a while..
