  Better hash function for unordered containers. Still a bit rubbish.

  On second thoughts, I'll just completely remove hash_value for ordered
  containers. It's low quality and not very generic (it uses boost::hash for
  mapped values). Should be a painless change.

differently to the standard associative containers, comparing keys
using the equality predicate rather than `operator==`. This is inconsistent
with the other containers but it is probably closer to user's expectations.
I have also added a `hash_value` free function so that the containers can be
hashed by [classref boost::hash].
