Player Engineers often build teleporters too close to walls

[Pelipoika]

Giants coming out of the teleporter may get stuck in a wall

[Kenzzer]

Soluces :
1 - Make an hull check before teleporting a robot or make an hull check for a 2.0 scaled robot before allowing to place a teleporter.
2 - Force players to build the teleporter and their sentry at the hints on the maps.

I'd like to make the last one, if you allow me I'll make a PR.
