[Feature Request] Less obtrusive "unhandled event" reporting for webclient

[InspectorCaracal]

Is your feature request related to a problem? Please describe.

Since the bug regarding the webclient's error-messaging was fixed, sending any unrecognized "commands" (e.g. text, prompt) results in a big, confusing error message being printed out to the user.

Describe the solution you'd like

Since this is initiated due to server-side handling and something useful only for development purposes, I think it would be better output to the browser console rather than printed to the game window.

Describe alternatives you've considered

It would potentially also be useful if the client reported the error back to the server to be logged there, since it is after all the result of an unrecognized command being sent from the server in the first place.
