Message in gop
Allow message box to be displayed in GOP
- needs testing-- try set/add/add2 to make sure it still displays correctly when the content of the msg box is changed, especially if the change extends beyond box boundaries
- make sure things like duplicating the subpatch don't mess up msg box gop display
- wait and see if Vanilla makes this change-- if not, add a little warning that this is only a Purr Data feature
