This commit accomplishes three different things:
- Makes it much less difficult to communicate service settings
between the UI and the plugin.
- Refactors some code and makes it cleaner and easier to modify to our
needs (although there is still a lot of work to do on that front
because of heavy code duplication issues between auto-config and the
stream settings pane).
- Significantly reatly reduces the number of times the json file has to
be opened and parsed.
This also kind of denotes a bit of a failure on the plugin communication
aspect. The properties system is too limited and jank for a lot of
things we would like to do at times.
