* Got rid of the problematic svg background which marginally worked on 0.14.7 but doesn't on 0.24.4

* Instead, using the existing msg border/background and adjusting its size dynamically

* The behavior remains identical to before (hide nlets, do not worry about readjusting patch cords)

* LATER: think about integrating patch cord and nlet adjustment to match vanilla behavior, consider further fine-tuning the text placement based on various zoom levels and fonts sizes (some still are a pixel off, this is true for also regular text objects), and finally implement this same approach for the regular text objects
