controlled phase door within LOS

[marvalis]

As long as you see where you are going, you should know where you are going to end up.
Currently, controlled phase door is much to random making it a bad skill. If you can choose the exact square within line of sight where you are going to be teleported too, then the skill can become the trademark mobility talent for archmages.

Targeting a square outside LOS should maintain a more random effect, since you have no idea where you are going.
