wip/zlua 1.8.12 NetBSD

z.lua is a faster way to navigate your filesystem. It tracks your most used directories, based on 'frecency'. After a short learning phase, z will take you to the most 'frecent' directory that matches ALL of the regexes given on the command line, in order.

For example, z foo bar would match /foo/bar but not /bar/foo.
