Airship Assault 1.0.0

Hello peoples,

I've been asked recently to create official instances that aren't release on rathena yet. So I decided to merge them to hercules too.

This is a version of Airship Assault instance, corrected from Ziu initial script.

It has been fully translated to english, reworked to be more clean and tested.

You'll find everything needed in the rar, including instance file, mob, item and quest db.

You'll still need up to date client (I personnaly use 20160201) to ensure the mobs are created client side.

Have fun.
