r194: Applied Bernard Jungen's patch, with a few modifications:
- Copy and move actions: checked directory not copied/moved
into itself.
- Full info display more a la RISC OS [ cftime -> strftime ]
- Added 'App' object type
- Aligned object type display
- Aligned object size display
- Added date display
- New windows open with last selected display options
(icons/sort/show hidden). My idea is that when the filer is
quit these options should be saved automatically and reloaded
on the next invocation...
[ style and sort_fn saved from options box ]
- Executing executable files first chdir to their location instead
of $HOME.
- Effective permissions in uppercase instead of between ()'s.
