Allow "long hands" when using the wand

[madmaxoft]

When using the wand, make the player capable of reaching far by using a cLineBlockTracer to find the actual block that has been clicked (just like a //hpos command). This will allow the player to select blocks without having to move towards them.

Bukkit has /farwand for that. It isn't that hard to implement. I'll do this.

I don't think we need a special type of wand for that, I don't see a reason not to use the normal wand.

Wel, that's how the default bukkit does it, so we should probably at least implement the /farwand command.
