Shiny update input diagram

[schloerke]

Fig 13.3 diagram has some odd text formatting.

Minor changes I'd like to make:

• "Rather complex" -> "Complex"; Or remove
• "Modal, notifications" wraps "notifications" to two lines. Can it be fit into one?
• "Locates the good handler" -> "Locates a valid handler" or "Locates the correct handler"

@DivadNojnarg Sorry for the unclear request...

Could the Modal, notifications, ... be

Modal,
notifications,
...

?

Thank you for the other changes!
