Closes #105

@antongolub, what about now ?

[Badisi]

@antongolub, I refactored a bit to check against '.' as you requested and added some tests.

Hey @Badisi,

I'll take a look in the next 24h.

[antongolub]

Everything seems fine. I'll merge this next morning to be able to rollback if needed.

@Badisi,

Merged. Could you plz make a couple tweak ups?

1. Introduce getRootPkgs(context) helper:

   const getRootPkgs = (context, ...extra) => getPkgRootOptions(context).map((pkgRoot) => {
   const manifestPath = cleanPath(`${pkgRoot}/package.json`, context.cwd);
       return {
           path: manifestPath,
           manifest: getManifest(manifestPath),
           ...extra, // _depsChanged: pkg._depsChanged,
       };
   }),

2. Rename getPkgRootOptions to getRootPkgs to define both helpers in one place.
3. Add some notes about config.pkgRoot. Docs ref would be ok.
