Pinboard selections work, as does clicking on the root window. And popup
menus.
Keys bound to menu entries are automatically saved when the filer quits.
The 'rox' script now just calls AppRun directly.
Panels can be created without starting a new copy of the filer.
The pinboard can be changed or removed by using --pinboard a second time.
Files can be given as arguments - they are opened as if they were clicked
on in a filer window (suggested by Alex Holden).  If no arguments are
given then the default is now the current directory (not your home
directory).
If you start the leafname in the path minibuffer with '.' then the Show
Hidden feature is temporarily turned on.
Pinned icons are now updated when the pointer moves over them, if necessary.
Drag and drop works properly.
