auto merge of #614 : alexcrichton/cargo/issue-613, r=brson
As described in #613, this commit switches the semantics of `cargo update foo`
to updating *only* `foo`, not any of its dependencies. A new flag,
`--aggressive` was added to restore the old behavior.
The behavior of attempting to only unlock `foo`, and then if resolve fails
unlock all dependencies of `foo` is unimplemented as it's not super relevant
right now when the majority of dependencies are git dependencies and resolution
cannot fail for version-related reasons.
Closes #613
