Patches for passwordmaker-cli

[snake66]

Not sure where to post this, so posting here

I've added some patches for myself to make passwordmaker-cli to compile cleanly (without warnings) on newer versions of gcc. I'm attaching them here in case you are interested. This is no functional change, but fixes a potential issue where destruction of objects of type CmdLineOutput or Visitor results in undefined behaviour.

With this patchset passwordmaker-cli now compiles cleanly with gcc 6.1.1.

I'll take a closer look on Monday.

And that's if I'm not coded out.

Great, thanks!
