[VL] Rapidly replace IOBoxes with Input, Output, Pad

vvvv beta feature

I saw ioboxes and pads can be replaced with each other.
would be nice to have the same with square Inputs and outputs as well

as a UI side question: is there a reason, that ioboxes can receive and send, just depending on the user choosing the upper or lower half of it while linking, but for Inputs/Outputs this is entirely different?

we have that one in the bug tracker since a while. IOBoxes and pad are internally the same thing, therefore its easy to transform one into the other. doing so with inputs and outputs and other available data hubs needs more thought on that… no ETA yet.
