Log Message:

Reorganize project, remove Postgres type hierarchy, bump version.

Currently this project attempts a rather great feat, providing a Python
counterpart to nearly every Postgres type. While admirable, its use is of
arguable benefit. Also, as Postgres changes, it becomes much more difficult to
make said types consistent with a given backend version.

With this commit, the project will change to be specifically concerned with the
packing and unpacking of Postgres types into standard Python types for drivers
that read object data off of the wire.
