Added a small framework for easily updating a list of all languages the repository contains a "Hello World" program in. See CONTRIBUTING.md for a command for updating the listing (using the list_langs.rb Ruby script).

When adding new "Hello World" programs, please name the file according to the language it was written in, don't abbreviate the language name too much (so use "JavaScript", not "JS") but don't make it TOO long (so use "CSS" not "Cascading Style Sheets". Use hyphens ("-") as word seperators, and only use a single dot (for seperating the filename from the extension). For exmaple, a "Hello World" program in Objective C should be named "Objective-C.m, and the one in HTML should be named HTML.html.
Use
cat README_nolist.md > README.md; echo >> README.md; echo "### This repository surrently contains "Hello World" programs in the following languages:" >> README.rb; ruby list_langs.rb >> README.md
for updating the list of languages in README.md.
