Add a --no-download flag to avoid fetching crates #7

Closed stevenjm closed 9 years ago

In theory, cargo-bootstrap would previously have worked in no-download mode, as long as all of the versions installed are the latest versions in the crates index. For use in a networkless environment, or a package build system that needs to be usable without networking, it's sometimes useful to have a set of pre-downloaded crates that satisfy dependencies without being the latest versions available.

This commit adds a --no-download flag which forces cargo-bootstrap to look only for locally downloaded versions of crates, and fail if a dependency cannot be resolved that way.

I've realised that this implementation is actually incomplete. In particular, it doesn't verify that the version available actually satisfies the required version range. I'll open a new PR once I've polished the patch a bit more.
