Added support for the "favorite item tab" feature. super-mega-thanks to Judas, credits to Fatal Error.
Be aware this update requires a new column in the inventory db, run upgrade_svn16517.sql in your database. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@16518 54d463be-8e91-2dee-dedb-b68131a5f0ec
