Add swipe actions to List View files and folders

[mpivchev]

This adds swipe actions.

Note: Originally we were supposed to have Share and Delete as actions, however Delete is very complex in that it can either be Delete or Leaving Share, and requires a confirmation dialog. IMO the swipe options should be for more simple actions that don't require additional confirmation and so on.

... where is the shortcut Delete ?

• maybe create NCCollectionViewCommon + (SwipeCollectionView)
• maybe create NCCollectionViewCommon + (SelectTabBarDelegate) the actual source code length is very too hight (over 2100 lines)

@marinofaggiana I added swipe to delete action, the only issue is that the deletion takes a long time.
