Goal nodes should not float too high

[stefanhendriks]

As noted in #17 playing FY_iceworld, you'd see that the CT and T spawn's are floating higher up in the sky. Bots cannot reach that and thus it messes up their pathfinding.

Best would be to do:

• pick vector
• check downwards until it hits something, pick that vector + some height (0,0,32) and that should be the goal vector

There is a function node_float, look into that?
