Hide same reference from Search Results Table

[ryanwwest]

When I open the table for a block with a reference, it always shows the same reference in the same file that I used to open the table in the first place. This can be a little annoying, as even though I can identify that it's just referencing itself by reading it/checking the filename, that isn't very helpful and takes time. It would be nice if we could optionally exclude that one (or at least clearly mark that it's the same reference).
