Feedback for errors transforming code or rendering

[krispya]

I'm hijacking this issue to expand its scope from just when nothing is rendered to when Triplex has an error trying to display the isolated component at all. Currently you get an empty scene with some error notifications which can be easy to miss (for example being tabbed away) or hard to understand (for example, why are is the HTML JSX giving me an error?). There should be better feedback to the user regarding why a scene failed to render. Some common examples:

• Opening a component with HTML JSX.
• Opening a component with context.

Great thanks, update as needed. If you search for "error" a few issues come up. https://github.com/trytriplex/triplex/issues?q=is%3Aissue+is%3Aopen+error
