/*
A few notes for future developement:
- A full implementation of gossip for GO's is required. They must have the same scripting capabilities as creatures. Basically,
there is no difference here (except that default text is chosen with `gameobject_template`.`data3` (for GO type2, different dataN for a few others)
- It's possible blacksmithing still require some tweaks and adjustments due to the way we _have_ to use reputation.
