#160 remove files after close that have a filesystem size of 0

[Bert Wesarg]

While I'm at it, here is a feature that remove files with e filesystem size of 0.

The user hase 3 options:
"Never":
never remove such file
"Prompt:"
prompt the user => "yes"/"no" choice
"Always:"
always remove such files

This global option can be selected in the 'Preferences' -> 'Default Settings' -> 'Remove Zero Sized Files' menu.

I use this with rejects files, so I don't forget to remove these after I solve all rejects after applying an patch.
