Persistent file mark

[gotar]

Sometimes it's necessary to make multiple time-consuming operations, like copy or move with common destination directory. It would be desirable to have an ability to mark files within multiple directories at once and issue and operation after that. Unfortunatelly marks disappear after directory change, so currently there's only one way to do this - via find file panelization (otherwise some hard scripting in user menu is required).

As mc already has clipboard, multiple screens, different histories etc. it's just one more structure to be added - file stack, and some bindings to append marked files, panelize and remove contents. All the operations like copy or move would be executed from panelization panel.
