Don't watch all sources of other packages in the same workspace, but only Cargo.* files

[Canop]

Right now, when you launch bacon on a package in a workspace, all the packages of that workspace are watched, even if they're not dependencies of the current package.

But it's probably enough to watch the Cargo.toml and Cargo.lock at the workspace level and in other packages of the workspace. Source/Test files in other packages which aren't dependencies can't impact the package.

Any different insight on that ?
