Add "go to file" for js imports/requires

[sdeleon28]

Should resolve module-resolver entries properly. Use babel-node's `require.resolve'.

[sdeleon28]

Implemented a resolver that can handle:

• Absolute imports using babel's require.resolve
• Relative imports adding a .js extension to the reference

Pending:

• Resolve references to index.js files that don't include the index part

[sdeleon28]

I could probably change the directory from which babel is calculating relative imports from. In that case, all I need to do is change the contents of the ___resolve.js script and use that method always (instead of manually calculating the path for relative imports).

[sdeleon28]

Otherwise, I can try to find the reference by inspecting filesystem contents. If adding .js results in a file, :edit that one. If it doesn't, try appending /index.js instead. If that still doesn't produce a file, show an error.

[sdeleon28]

I should also change the name of ___resolve.js to something even more unlikely to exist.

• Try doing the resolution by using babel only
• Otherwise, try resolving manually
• Rename ___resolve.js
