Better value, class and metaclass representations (now they follow the enumeration values).
Fixed __getitem__ to raise KeyError.
Getting class and metaclass bases (need of a new decorator to get rid of stupid `unbound method` on Py2k)
All enumeration methods now use the `NoUnbound` decorator. Moved `NoUnbound` to tools (and new `no_unbound` helper) (+ tests).
Added comparison support (and hash, int) (+ tests).
`long` is now an accepted enum type (WTF they were thinking? Why long is not subclass of int?)
Pickle support for enum elements (+ tests)
Fixed ordering of parse on multiple objects in the same file (+ tests)
Better description and keywords
