[searchResultList] Sticky results per page

[mgrani]

I often encounter the problem that paragraphs bring similar results (E.g. similar images), but that no paragraph gives me all images i want to view. As a solution i would allow users to set results as "Sticky". Sticky results will be displayed in addition to new results that are returned by a new query and should be marked with a sticky icon (e.g. a pin). Sticky results might be remembered in the backend (would require a post message to the backend) per Web Page and visualised as a collection.

I rate this feature as high impact and should be realised next (of course that is to discuss :).
