Dependency importing

[Alloyed]

Sometimes you want to patch a dependency
The way to do this with minimal hassle is to copy the modules you want to change into your main folder, so you can revision control it and keep loverocks from touching it. (you can also vendor the dependency but that's a lot of bookwork for something that might only get used in one project)
it'd be nice if loverocks could:

1. do the copying step for you
2. pin the version it copied so you don't accidentally update only half the module
