Release v1.0.17 (#9)

* add shortcut -H to --no-headers, it's too cumbersome to type * added fuzzy search support * Added basic lisp plugin facilities * Lisp plugin Addidions: - added process hook facilities - added working example lisp plugin for filter hook - load-path can now be a file as well - added a couple of lisp helper functions (atoi, split), more may follow, see lisplib.go * linting fixes
