This allows getting rid of serialized/serialize.php. I also moved includes/normal/Utf8CaseGenerate.php to maintenance/language/ generateUtf8Case.php and updated it to subclass Maintenance, as it seems to be largely unrelated to normalization. Using version 6.0.0 of UnicodeData.txt, the updated script generates exactly the same serialized output as was previously checked in. Also updated the Makefile to reflect the current set of .ser files and added some .gitignore entries. Change-Id: I05afece3dc4505a9f43993ac4d7726b37d9c6956
