Auto grow growable nodes when ending a wire.

[TheQ]

When wiring to a growable node that is currently full requires you to either pull the node bigger first and then wire or wire and create a wire stub, then pull it larger and the Connect the stub to the terminal. 

Instead change the behavior so, if wiring is started and ends over a growable node, the node will grow automatically and add the wire being created to the new terminal. 

For example: starting an error wire and ending on a merge that is currently full, the node automagically grows by one and adds the wire to the new (last) terminal.

This idea is a bit more general, but seems to be mostly duplicate of this:

Auto-grow build array, string concatenate, build cluster, interleave arrays, build matrix, compound ...

Hesitation about this kind of idea because of bad experiences with the dynamic data type back in LV7.0 time frame (back when that type was new and might have been a good idea). The nodes for merging dynamic data type still exist and do this sort of thing. It was... kind of over zealous. IDK, maybe it was just that it was different.
