Fix multiuser LastPass extraction, print/vprint cleanup

I believe I broke this during my initial refactor, but I noticed that extraction wouldn't work if multiple users were found -- it was only extracting the last one.  This works now.  I also cleaned up the ```print_``` and ```vprint_``` to make for a more consistent experience.

This still doesn't work for me when trying to loot Firefox on Windows.  Everything I can find says I have the non-binary version of Lastpass installed.
