Internet connection detection in GUI #656
Description
When the internet was unstable and I was working in the new GUI, the map was having issues. First, the fetch request was hanging resulting in a delay in opening the application. Then, the map was unable to display and any functionality related to it was causing errors. I think we need to detect whether the user has an internet connect and properly disable any related internet features. Examples of such features would be the map being made invisible and download buttons being disabled.
