[winswitch] DMG available download is not signed

[Gowtham Narisipalli]

I am using OSX El Caption and attempted to install xpra after downloading
the dmg.  Looks like the DMG is not signed as OSX is not able to identify
the developer of the application.  Can you please sign the package to
ensure that users who are downloading package can trust it and not fear
that it  tinkered with?

Thanks,
