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
