Add support for hive versions

[h4v0kh3l1]

Long-term thinking here:

Hive introduces its sql features across many versions, and we'll have users that need to pin to a specific version. The hive parser should add version to its query info, to know when to enable or disable certain parsing features.

We could give the Hive type a type-level version parameter.

re: #54 we'll want to support dialect versions for all our dialects, since everything changes eventually =)
