Currently NSIS allows only to delete empty directories (which is good). But in some rare cases it would be needed to delete a whole directory anyway. I propose to introduce a -f(orce) option that wipes the whole thing.
The problem case I have is that I have a "data" subdirectory which contains an arbitrary directory whose name depends on the used portnumber. So I'd like to be able to wipe the "data" directory brutally not caring what's in there.
