Remove teleblocks from certain teleportation methods

[Erik]

Most teleportation methods require someone to actually travel to the area first, the teleporter pad built by mechanics and the little teleport beacons used by the old teleporter both require you to actually go to a area first, and build a pad, or leave a beacon behind.

I don't see why these methods should be blocked as well, it would be way easier for a scientist to travel to the solarium, setup a beacon, or leave a pad behind and allow players to go there without having to use telescience.
