Warning: this branch commit is largely untested, and known to throw exceptions as database structure retrieval is currently missing!
Further work on SPMySQLFramework integration: - Improve SPMySQL framework build settings including correct ppc builds and a Distribution configuration for the build distributions to match - Add new convenience querying and result methods to the framework - Amend Sequel Pro source to use the new SPMySQL.framework methods everywhere, replacing MCPKit methods where they differ and improving some functions - Remove MCPKit from the source - Fix a number of warnings on Release-style builds
