[Feature Request] Create new playlist out of search results

[thingsiplay]

Description

It would be very helpful to easily create new playlists for specific use cases. Whenever a search is performed on any playlist or in the "Explore" tab, a result with game titles will appear filtered by the current search. All of this is in memory and could be used to generate a new playlist from it. It could even use the default core or the core the game has setup and mix different systems into single playlist.

Edit: An alternative idea is to save the search results as "Save search history as Live search". Which only saves the search history that lead to these results and would do a new search with same keywords and settings again. Advantage over playlists is, that it will show you the newest entries without updating a file. But it could be slower off course.

Expected behavior

Do a filter in a playlist or search in Explore and click on a button named "Export search results as a playlist" to save it to a new playlist.

Actual behavior

--- Nothing. Functionality is not implemented. ---
