Dedicated page for JavaScript invoked on server-side

[rosieks]

SpaServices project provides ability to run JavaScript on server. When such invocation failed the following error is displayed.

It would be nice to have dedicated page that focus on JavaScript error and provide nicefied stacktrace, current npm version, etc

@SteveSandersonMS any thoughts on this? We've been thinking of some diagnostics pages extensibility in general, for example: #403

It would definitely be good to present this information more readably - the stack trace at least.

If the new diagnostics extensibility point issued a call back to get the nicely formatted error info, passing the original exception, then it would be easy enough to embed whatever info we need into the NodeInvocationException and pull it out.

Ok, we'll consider something for 2.1.0 then.
