Ignore dependencies of a dependency when using volo add

[foxbunny]

I have a package that is a dependency of one of my projects. It depends on BackboneJS. When I want to reinstall just that package with -f, it pulls in BackboneJS and all of its dependencies. This is quite slow when I'm just testing a bugfix in that package. It would be uber-convenient if there was a command-line option to ignore all of the package's dependencies in this case.

+1. Would be nice to install some lib without the dependencies!
