Display file shortcut name with shortcut name, not original doc name

[samjacoby]

Feature

I'd like to be able to list a file shortcut in a directory index, and display the included file with the shortcut name, rather than the original file name, e.g:

1. I create a shortcut in a directory that has a library index page
2. I rename the file from Foo to Foo Shortcut
3. I expect the file to be listed in the index as Foo Shortcut, but instead I see Foo, regardless of the shortcut name.
