Game Mechanics: Should be able to target invs/hidden players if you have see invis

[Lostfaction]

assumed asking rogues if they had sneak on when /rt fails a buff request was just part of life at this point

[nilbog]

Found and fixed the following cases:

Players with see invisible active can now acquire targets via /target playername for:
-Rogues in a hidden state
-Players using Sneak when positioned in the rear arc


If there are other cases, post it up with steps to replicate.
