Make our File>Recent Documents work better when sandboxed

Store security scope bookmarks for files selected in the file picker
in the user data. (I looked into storing it in the LO "registry" in
the Histories/PickList thingies, but that was horribly complex.)

When opening a file, if we have stored a security scope bookmark for
it, use that while opening the file.
