RDM weapon rework.

[Tlamila]

Currently the Paladins are about the only class that uses the shield slot, its just an empty slot for everyone else. This would add another class that would use that slot and give us more ways to customize our RDM.
While the sword would have the intelligence and damage stats the crystals would have the magic defense stats and all.

DoH and DoL use it as well, for the offhand tool.

I disagree with the suggestion, as said they removed the system even from WHM and BLM because it was pretty meh. Even when it was still a thing, as a WHM I would always choose 2h staff rather than wand and shield.
