- Modified main.sql to add 4 missing indexes (thanks to ErkDog): char_id on the tables memo/friends, and online/name on the char table. Added upgrade_svn8728.sql to add these indexes to already existing tables.
- Changed back the default of case-sensitive to ON since it shouldn't be such a bad performance hog now.
