sw define bibliography entry dialog, file picker: handle relative URLs

On one hand, if we have a setting at tools -> options -> load/save ->
general -> Save URLs relative to file system, then let's be consistent
and handle that setting here as well.

On the other hand, this is the default, so this helps the scenario where
a bunch of PDFs are in a directory, a document is next to them, and
copying all of them to a different location doesn't break these links.
