This changeset implements renaming and duplicating databases on a server. Details as follows:
* altered MCPConnection listTablesFromDB:like: to return NSArray * altered MCPConnection listFieldsFromTable:like: to use backtick quoted strings for table and fieldnames * added MCPConnection listTablesFromDB for a complete table list * added SPStringAdditions.h to various files to prevent warnings * added sheets for duplicate/rename DB in DBView.xib * added duplicate/rename menu items to MainMenu.xib * added outlets in TableDocument: databaseNewSheet databaseRenameSheet databaseCopyNameField databaseRenameNameField copyOnlyStructureButton copyDatabaseButton renameDatabaseButton * added methods in TableDocument: getConnection, copyDatabase, renameDatabase, _copyDatabase, _renameDatabase * added OCMock Framework for object mocking in tests * added group Others/DatabaseActions
