Support keep package.json's version

[FinnWinchester]

So we are using some dependencies installed directly from a private repository (as in "package": "git+ssh+blablabla.git#v1.13.2".

I would like the reinstall command (reinstall --save package) to maintain the original package.json's version of the package I am about to reinstall. What it does instead is pulling last npm version from npm registry.
