`ReadOnlyDict` not pickleable

See original GitHub issue

Example:

import pickle
import sacred

cfg = sacred.config.custom_containers.ReadOnlyDict({'foo': {'fizz': 'buzz'}})
cfg_pkl = pickle.dumps(cfg)
cfg_depkl = pickle.loads(cfg_pkl)

Error:

Traceback (most recent call last):
  File "sacred_err2.py", line 6, in <module>
    cfg_depkl = pickle.loads(cfg_pkl)
  File ".../lib/python3.6/site-packages/sacred/config/custom_containers.py", line 232, in _readonly
    self.message,
AttributeError: 'ReadOnlyDict' object has no attribute 'message'

I think custom __getstate__ and __setstate__ methods need to be added. I suspect this will also be a problem for some of the other ReadOnlyContainers.
