jsonpointer will not work with unicode keys in python 2.7

[maxsmythe]

It looks like jsonpointer will not work with unicode keys, both of the following code snippets fail:

data = {u'\xee': u'\xee'}
jsonpatch.make_patch({}, data)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/sendhub/scratch/contacts_v2_scratch/venv/local/lib/python2.7/site-packages/jsonpatch.py", line 171, in make_patch
    return JsonPatch.from_diff(src, dst)

data2 = {u'\xee'.encode('utf-8'): u'\xee'.encode('utf-8')}
jsonpatch.make_patch({}, data2)

Thanks for the report! I've release jsonpointer-1.9 and jsonpatch-1.10 which fix this issue.
