This is it, the long-awaited huge commit with the new Network handling.

This is it, the long-awaited huge commit with the new Network handling.
Besides the new settings page, the underlying structures have muchly improved.
To connect to a network, please use the new settings page (F7) for now; I'll add
a more convenient way soon. Ah, and connection failures are now reported and handled
sanely (auto reconnect is not yet implemented though) :)
Your old settings will be mostly migrated. Good luck.
