It would be great if we could have a new attribute for the <Page> element called import that lets us specify a module name to require/import, instead of it searching for a filename.

This will be very helpful in implementing a clean directory structure.

Also an extension on #1667; codeFile breaks in bundlers like webpack since bundles are by definition single-file. import fixes this by importing with global.loadModule.

@enchev, IIRC you were talking about turning CSS into modules for webpack and this could lend itself to that too by doing the same with a new stylesheet attribute -- with module.exports being a string.
