Dont show absouloute path for files in quick-open

Currently quick-open has two columns for results: Filename : Filepath. Full filepath is shown which completely breaks the UI sometimes when there isn't enough space and the columns aren't resized properly. This is a first step in partially fixing this situation.

Ideally, imo, it would be nice to have just one column for results with file path either below the filename or by it's side in a dimmed color to increase the focus on what's more important.
