• Revised db_generate.sql
• Added a note to db_upgrade.sql to refer to admin/admin_upgrade.php.
• Revised the contents of admin_upgrade_0_18_0 to make sure it includes all changes. (didn't worry much about the indices)

NOTE: We need to do the following work:

• Compare db_generate.sql from 0.17.5 with this db_generate.sql to make sure that all changes are approved before 0.18.0 is released.
• Revise db_add_indexes_2002-06-07.sql and absorb some of it into the schema, then delete the file.
