#3 Entry field presettings for copy/move action

[Daniel Scheibli]

This patch modifies the entry field presetting for the copy (F5) / move (F6) action for those cases where no directory/file is selected.

In such cases the current behaviour is to put <DESTINATION_DIRECTORY> in the entry field and to take the current cursor position in the source directory as selection. This patch (inspired by the Total Commander behaviour) is proposing to change that to <DESTINATION_DIRECTORY>/<FILE>. That way one can do regular copies/moves as well as ones where the file gets renamed.
