need and ensure htag>=0.9.20

- the service.PopMenu has got a higher z-index : should be displayed well over alert box ;-)
- the service.PopMenu/background is now closed on right-click (no more default menu)
- need htag 0.9.20 : use self.call() instead of good old self()
- need htag 0.9.20 : generated IIFE scripts use the `self` var instead of `tag`
