Give these crates each a more standard directory layout with sources in a 'src' sub-sirectory and Cargo.toml in the top lib/foo directory. Add license and description fields to each. The build script for the cretonne crate now lives in 'lib/cretonne/build.rs' separating it from the normal library sources under 'lib/cretonne/src'.
