Please package `src` alongside the app

I just got a really great error message:
```
An unhandled rejection has occurred inside Forge:

I was like, oh cool! Source maps worked correctly, I can look at the TypeScript to see what was happening when the error happened! Except I can't, because this package doesn't publish its sources. `/home/iameli/code/aquareum/node_modules/electron-winstaller/src/spawn-promise.ts` does not exist. May I suggest that adding (`tar cz src | wc -c` ==) 6473 bytes to the distributed package would make lives a bit easier?
