Add support for the different metadata versions specified in PEPs
241, 314, and 345. Distributions now parse and expose only the attributes
corresponding to their metadata version, which defaults to the version
parsed from the PKG-INFO file. The programmer can override that version
when creating the distribution object.
Add support for introspection of "development eggs" (checkouts with PKG-INFO, perhaps created via setup.py develop).
