Moved card0 check to config & Flux lib

* Fixed rathena#190
* The card0 values are defined in config file (application.php) in `ItemSpecial`. By default, using rAthena's card0 values.
* The usage will be `Flux::itemIsSpecial($item)`. Returns `true` if item's card0 is special, `false` otherwise
* For control checking (ifs) for item is forged
  * `if ($item->card0 == $this->itemIsForged)`
  * `if ($item->card0 == $this->itemIsCreation)`
  * `if ($item->card0 == $this->itemIsPetEgg)`
