Window sizing

[bm-hellorobot]

1. With different monitor sizes (eg large desktop vs macbook) the interface doesn't always scale the way I would like. On small displays, the non-camera UI elements usually feel far too large, and I need to zoom out to ~67% to make everything feel equivalent to the look on a large monitor.
2. The resizing of the cameras on startup takes a significant amount of time, sometimes 10-20 seconds before things stop bouncing around the screen.
3. When the connection gets spotty, the cameras start trying to dynamically resize themselves again, which is pretty frustrating as it can cause the buttons you're trying to click on to move around.
