Previous versions used the "last output directory" when opening the "Browse"
dialog in the main window, using the current "File name" only if the "last
output directory " is not yet defined. This change reverses this, which means
that the folder of the path currently entered as the "File name" will be used
as the folder to display. The file name will be carried over to the dialog.
Fixes#372 .
