[BUG] "functional change" to __hash__

[lurch]

OS version:
Ubuntu 14.04.6 x64

Python3 version (python3 -V -V):
Python 3.6.8 (default, Dec 25 2018, 00:00:00)
[GCC 4.8.4]

Steps to reproduce:

>>> from frozendict import frozendict
>>> fd1 = frozendict({'a': 'b', 1:2})
>>> fd2 = frozendict({'a': 'b', 1:2})
>>> fd3 = frozendict({1:2, 'a': 'b'})
>>> fd1 == fd2
True
>>> fd2 == fd3
True
>>> fd1 == fd3
True
>>> hash(fd1)
7248413867072730019
>>> hash(fd2)
7248413867072730019
>>> hash(fd3)
6961149576487961955

Note that fd2 == fd3 but hash(fd2) != hash(fd3). When I tried running this code yesterday (prior to 0125b86 ) the hash values for fd2 and fd3 equalled (hash(fd2) == hash(fd3)).

Ok, now I remember why the first time I considered to use tuple and I dismissed it...

Fixed with 10303a8.
