[docs] [issue21782] hashable documentation error: shouldn't mention id

[Giacomo Alzetta]

New submission from Giacomo Alzetta:

The documentation for hashable in the glossary (https://docs.python.org/3.4/reference/datamodel.html#object.__hash__) is incorrect:

they all compare unequal (except with themselves), **and their hash value is their id().**

It is *not* true that their hash is their id (see relevant SO question: http://stackoverflow.com/questions/24249729/user-defined-class-hash-and-id-and-doc)

Also the documentation for __hash__ (https://docs.python.org/3.4/reference/datamodel.html#object.__hash__) doesn't even mention id().
