Final feature work on the SPMySQL branch before merging:

 - Add a ping keepalive managing object to prevent retain cycles from the NSTimer
 - Add -[SPMySQLConnection copy] support
 - Refactor Hans-Jörg Bibiko's database structure retrieval, moving it out of the MySQL framework and building it around a copy of the connection.  This reduces the amount of connections-over-time used by Sequel Pro to two constant connections (addressing Issue #1097) and improves robustness.
 - Use the database structure retrieval connection for faster query cancellation without an extra connection required, if possible
