Need an option to ignore private packages

[simongong]

If private packages(a.k.a. scoped packages) are used in a project, running

$ npm-shrinkwrap

will end up with

removing xxx/node_modules/@scope
installing  xxx/node_modules/@scope/package http://registry.npm.scope.com/package/download/
spawn /bin/sh ENOENT
something went wrong. Did not write npm-shrinkwrap.json

How about adding an option to the cli, like $ npm-shrinkwrap --ignore-private, which means ignore the correctness check for scoped packages.

Thanks.
