In flight request indicator

[KvotheBloodless]

With some resource providers such as the signalk-activecaptain-resources, loading a note type resource can require a downstream request to retrieve the data. On occasion, the downstream request can take a couple of seconds to return. The effect for the FB user is simply that nothing appears to happen and they are unsure if their action registered until the note detail popup finally appears. If the user is impatient, they may have already clicked on the note icon a few more times triggering more requests.

It would improve UX if there was some sort of visual indication to reassure the user that something is happening in the background. Ideally this would just be a spinner or something somewhere discreet in the UI that does not prevent the user from interacting further with the application while waiting.

This is of course not limited to loading note resources, it could be useful for any kind of background network activity.

Will add progess bar at top of screen (pink bar in screenshot) so it doesn't interfere with the rest of the screen.
Whilst not so noticable in a static screen shot, it's animated and quite visible in operation.
