Controller handles content as unicode in python 3.x

I am getting some errors when using Stem with Python 3 when iterating though all values return from controller.get_server_descriptors(). The error happens in /usr/local/lib/python3.2/dist-packages/stem/descriptor/server_descriptor.py . I have fixed some of these errors (see attached file) but I think there are more problems with the way the "digest" variable is created. For example, if self.digest() returns 0222F10950D2177B99288E9D133FAB1B0848AE70, the digest variable is given the value

b'{q#a3l\xb9\xa7,\xb5\xf0EX\xa9\xca\xd6\xe1\xae!\x10'

but the proper encoding would be

b'\x02"\xf1\tP\xd2\x17{\x99(\x8e\x9d\x13?\xab\x1b\x08H\xaep'

I should also note that I have not tested this patch with Python 2.x yet.

This is the error which still happens with some digests:
