Initial commit of PostgresKit, our new Postgres framework as a start towards adding PostgreSQL support to Sequel Pro.

Note, that the framerwork is by no means feature complete and in it's current state has quite a few limitations:

- No support for Postgres' asynchronous query API
- Only supports the very basic data types (char/text and numerics)
- No support (outide of libpq) for re-establishing dropped connections

Current feature support includes:

- Basic connection handling
- Query execution
- Prepared statement execution
- Encoding support similar to SPMySQL's
