Subject: [PATCH 1/2] Create yes.lua

Lua implementation of functionality provided by yes command from GNU coreutils. However it doesn't use any of GNU, so it is not forcing GPLv3+ license.

It has full functionality but options had to been changed to single letter (like -h instead of original --help in GNU). Main use case requires piping, but works without it.

I have also created man page, but I have to send it in different pull request (don't know how to do it in github webpage).
