JSX compilation errors during bundling should reveal more information in traceback

[Thomas Lackner]

The react-page error handler helpfully shows you stack traces when things go wrong, but in the case of a compilation error with one of your .jsx files, the error is less than helpful:

SyntaxError: Unexpected identifier

In this case, lump/react-page/src/view/index.js was at fault - I didn't use the @jsx comment correctly. But that's hard to tell from the stack trace shown here.

BTW, renderReactPage.js:91:12 is the vm.runInNewContext() stuff.
