* When pk_mode and pk_mode_mes is enabled, the player gets notified joining a pk-zone map.
* It's now possible to specify the target in showscript.
Default is still AREA.
* pk_mode_mes is now using showscript to SELF.
* Thanks to @Atemo, @RadianFord, @Lemongrass3110, @aleos89
* Fixes#2445 and fixes#2446.
* Fixed shadow refiner.
— The script uses the values of the array instead of the indexes to loop through it.
* Fixed segfault in getequiprefinecost.
— No checks in getequiprefinecost meant there were possibilities using negative indexes in arrays.
* Added to the script documentation what happens on failure when calling getequiprefinecost (it returns -1).
Thanks to @vstmpf, @crazystorm2017, and @hendra814!
* Converted refine_db.txt to refine_db.yml
* Refine success rates can now be set in refine_db.yml. rAthena's default NPCs will respect this database by default.
* Added shadow equipment refiner
Thanks to @Akkarinage @aleos89 @Atemo and @Mikegyver for their inputs.
