[Systems] Trac spam cleanup

[Bernie Innocenti]

 <silbe> bernie_: can you issue "delete from ticket_change where author
 in ('nikecitycn', 'sunrise');" on the trac db (using sqlite3), please?
 from looking at the database schema it should cause no side effects but
 i don't know Trac well so would recommend to do a backup of the
 database (file) first.

Done. Thanks for reporting this.
