* Fix gossip menu options for client version 1.5

Decompiled 1.5 client code shows that...
1. The icon is read as a 32-bit integer instead of 8-bit.
2. The "coded" field is not read at all, indicating that that field was
added in patch 1.6. This lines up with the Blue Murloc Egg being likely
the first item obtainable by gossip-code in late 2005.
Before this change, opening a gossip menu with options would crash the
client.

* Correct version check style

Before patch 1.7, Orb of Deception was applied as a Dummy aura instead
of a Transform aura. Otherwise the spell is nearly identical, so we
simply reuse the existing Transform aura handling.

Should fix AV becoming totally broken after running for multiple days.

It was weirdly teleporting to a proximate location based on boundingradius and conserving teleported player orientation.
Much more convenient for testing and gm activity to teleport to accurate pos

On official servers if you get invited to a group while already in an instance, that save persists through logout while grouped, even though its a personal save. If there is no group save created yet, it will persist through leaving and entering the dungeon as well. Its only reset once you exit the dungeon when there already is a group save.

Only for those not currently inside their personal saves.

The database values based on classic sniffs are completely fine.

Closes #2392

In classic you get an error message and it doesn't let you cast it, instead of casting it and causing flag to drop. The attribute that I believe controls this was only added to immunity spells in patch 1.9, so that would indicate it was possible to bop people to make them drop flag in early vanilla.
