GOP abstraction refresh
When there are several copies of the same gop-abstraction in a (sub)patch and the abstraction template is saved, the gui isn't updated. Only when the (sub)patch is closed and opened again. Also other cables etc. aren't displayed properly. That means, when a gop changes from the inside, the patch needs a proper refresh. This also affects display of guis inside gop. I'm sending commands to a hradio, and they aren't displayed - but the messages go through. When this happens, pd has to be restarted to work again. Restarting the patch doesn't help enough.
