Ignore case when filtering out current file name from local trailer search.
Added support for Trailers from My Videos Title and Shares view. If the corresponding item in Shares view is not in the database it will have no 'title', to better handle that some checks are in place to ignore searching for trailers by title.

Note: In Shares view the #file property is not set, in this case we get from the selected item in the facade as MyVideos sets the Path property.
