Merge pull request #40 from crosbymichael/api-readme

Update readme with API change explination
Updated libcontainer subpackage dependencies. Most subpackages now do not depend on their parent ('libcontainer') package. 'namespaces' and 'nsinit' still do.
'namespaces' need to refactored a bit more to move the API part of it to 'libcontainer' package and keep the namespace specific code inside that package.
This change is not expected to break docker.
