[Feature Request] Add a Prefs Windows to manage stored Wi-Fi networks

[williambj1]

Is your feature request related to a problem? Please describe.
Now we can remember Wi-Fi networks and automatically connect them. It would be nice if we could manage them directly in the App instead of messing around with System Keychains.

Describe the solution you'd like
An NSWindow with an NSTable that lists all the known Wi-Fi networks with a delete sign on the bottom right corner, users can delete the highlighted network.

Additional context
We would probably add more features to the prefs window such as controlling auto-updates, showing network username and password, etc.

This feature will be present in v1.0.1
