Someone had some problems with Evilfairy's script, so I took a look at it and decided to make my own.
In contrast to the "not core mod", "not database" idea, I decided to make this script editable through database and made it a core modification so I could just tweak the base gossip system slightly.
This modification allows multi vendors to be edited and created totally through database AND C++.
You can have multiple options to open different vendors.
You can use all normal other gossip as well, this does not close other possibilities.
YOU CAN send vendors also from C++ code, read the readme.
This script does not add new database tables or columns!
