needed.

Don't crash when I create new PipeTypes

I am using reflection to "hack in" new PipeTypes for myself.
(Yes, that IS possible, but very "aggressive")

Don't cause an ArrayIndexOutOfBounds exception when I do that.
(at least when rendering, just don't place a gate on my pipes)

This is also another step towards
the ability to create new PipeTypes.
