Fixed bug #361 again (parent_id of log entry cr_items point to case's object), this time providing an upgrade script, changing the parent_id of existing log entries, and fixing the case deletion proc to delete cases properly given the parent_id.
cleaned up files: updated require sections, removed references to arsdigita and openforce, and replaced out-of-date owner info. Most of these edits were done by hand due to bug 1106; I tried to do the same things the APM would do (remove file sections, etc) and updating the release date to today
