Support for multi module project

I’m having some problems with a multi module project and kotlin2js.

My main module depends on my other module using compile project(":common") which makes it compile just fine but the output javascript file tries to import the other project using require('common') which fails since there is no module named common. For now I’ve just set the output file of common to be node_modules/common.js but it would like to find a better solution to this problem.

That is expected behavior.
Use external tools like webpack for bundling.
