MacOS menubar app

[Ragnar Rova]

Hello,

I wrote a minimal macOS menubar app to control OpenConnect:

https://github.com/rrva/openconnectui2

It uses a privileged helper to run the parts requiring root and that
in turn uses --setuid to drop privileges. It uses the login keychain
to store passwords. For now, it does not run the vpnc script on
disconnect but rather some custom code to clean up routes, interfaces,
dns entries. It does not support any extra config settings besides the
bare minimum.

Please let me know what you think
