Networks module
This adds a Networks module to the System menu. It has 3 tabs:
- Network Connections, shows active and available connections. Allows editing, activating/deactivating, and deleting existing connections.
- Nearby Wi-Fi Networks, shows the wifi scan list. Selecting one will bring up the add wifi form with most of the fields already filled out with common options.
- Add Connection, to create a new ethernet or wifi connection. Infrastructure, AP, and adhoc modes are supported for wifi.
These changes will add 2 dependencies: python3-dbus and python3-networkmanager. But note that python3-networkmanager is not currently being built in Debian (only python-networkmanager). I've opened a bug report (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=777516) to add the python3 package.
