Lazily support TS hook files

Fixes #163

I've applied this same change-set locally, and it works as-described. It should be noted that you must have "module": "CommonJS" in your tsconfig.json's compilerOptions, as this is a requirement for ts-node to resolve properly.

Unfortunately, the local tests don't seem to run for me at all - so I am unclear why the metaverse tests are failing, as I can't reproduce. (I'm on a Mac? Maybe that's why?)

Is there any chance this might get some attention soon? It would be a nice feature addition. :)
