Option to stay on hidden page even if rotationHomePage is set.

[lxne]

Is your feature request related to a problem? Why do you want this feature?

In 'normal' mode I want my mirror to switch back to the homepage after being on another page for some time but I don't want it to automatically switch back from a hidden page.

Describe the solution you'd like

A new option e.g.: rotateHomeHidden: boolean,

Additional context

Additionally it would be handy if the notification HOME_PAGE had an optional boolean. If no boolean is set, pages switches to home only from other 'normal' pages. If boolean is set to 1, pages also switches to home from hidden pages.

Sounds reasonable. Looking for PRs.
