station: make autoconnect settable via debug interface

This adds the property "AutoConnect" to the station debug interface
which can be read/written to disable or enable autoconnect globally.
As one would expect this property is only going to be used for testing
hence why it was put on the debug interface. Mosts tests disable
autoconnect (or they should) because it leads to unexpected connections.
