Info GUI
- Add 'Info' button to toggle more detailed info in the GUI. Refresh button removed in favor of automatic refresh (coming soon).
- Update GUI to take advantage of TOML messaging additions to the service-monitor
- Add 'Help' button that access a page for short how-to. Only the back button is on that page now.
- After starting/stopping a service the selection is maintained instead of deselecting when the table updates.
