Switch to pkg_resources for compatibility check

Browse source 
Plugin Manager now internally uses pkg_resources.parse_version and
pkg_resources.parse_requirements to check for version compatibility
with plugins from the repository. That will allow to directly use
the OctoPrint version string once it's PEP440 compatible.
