Specific Warp Points for entering Warp

Warping out of a playfield is too easy.

If you make people work harder for it more interesting things will happen.

Right now if you are chasing someone around in space and they want to escape they just warp out to another playfield that is usually really hard to identify.

If you had to go to a certain location in the playfield (warp point) to get out that would be much more interesting.
