[ViewProperties] Apply better default roles for special views

This adds the following additional special view modes (some of them were
already there but broken because they weren't applied, or were
changed to have better defaults now that they are actually used):

* Recent Files and Recent Documents, timeline:
  Details view with grouped sorting enabled and Name, Path, Modified
* Search For Images:
  Icon view with Name, Dimensions, Date Time of the Picture
* Search For Audio:
  Details view with Name, Artist, Album, Duration
* Search For Videos:
  Icon view with just Name
* Search For everything else, including Documents:
  Details view with Name, Path, Modified
* Trash:
  Details view with Name, (Original) Path, Deletion Time
