I found, that I use two view settings. But switching between them means I have
to click three toolbar buttons. So I made one button for that.

Real world scenario looks like this: I open unknown book in PDF and click
"Book" preset. Now I see pages as in real bok and I can easily browse this book
using PgUp/PgDown to get idea, what it contains. But since my laptop display
has only 14", reading is a bit hard, so I want to "zoom-in" when something
interesting is found. But simple zoom is not enough, when interesting
information is around bage break, so I want to switch to continuous mode and
also to single page view (instead of facing pages) -- now I have "Reading"
preset.

This feature is not meant to replace current view options, only to make their
changing faster. It is in the same category as warpping mouse pointer from
bottom to top when scrolling down. I think it would be nice complement for
current zoom buttons on toolbar in default configuration. Actualy, I do not use
zoom much, only switching between "fit page" and "fit width".

Last button is for other very common use case -- overview of presentation
slides. I've added it mostly for a consistency, but I use that settings very
often too (when I have slides to read).

Also, I tried to implement it as least invasive as possible to minimize
maintenance costs of this code -- it triggers existing KToggleEvents.
