* Some preparations for the guild script update

- cleaned up npc event execution code
- cleaned up guild data loading/saving code; to be improved later
- removed dummy 'account name' expulsion list management code
- removed columns 'rsv1' and 'rsv2' from guild member data
- removed columns 'rsv1' 'rsv2' 'rsv3' and 'acc' from guild expulsion data
- added upgrade_svn11895.sql for SQL
