Improved the Schematic class. Added support for reading schematic files. That functionality still needs to be integrated and tested. Made minor changes to WorldOperation and its derived classes. Also fixed a few bugs in Schematic's export functions that were found during testing. The exporting code still doesn't do all the changes (e.g. block standardization) that had been implemented before.
