Fix some issues that were discovered while working on a flatpak

Testing Done:
built a flatpak (that'll be a separate review request) and ran into some issues..

First was bonjour_ft wouldn't build, not sure how/why that isn't happening elsewhere.. but whatever..

Next was the network monitor stuff I moved us to way back in december of 2015 works, but under flatpak the network is initially unavailable but then becomes available. A bunch of our code was __only__ checking network availability at startup and then not listening for changes later. This code is really gross right now, but a lot of it is going to need some major refactoring where as this effort was just to get this going right now.
