search-display: Move SearchResults to a separate file

Browse Source 
With the new layout, search results will be displayed in an independent
view like window previews, applications and possible future additions;
it does not make much sense keeping it with the switching logic, so move
the code to its own file.

Also remove the dash-prefix from the relevant style classes.
