add ineverylang puzzle completion

**What does your Instant Answer do?**
It checks to see if the user is searching for a popular programming puzzle, and finds solutions from http://www.ineverylang.com. If it can, it even pulls the solution for that user's specific search.

**What problem does your Instant Answer solve (Why is it better than organic links)?**
Rich code solutions, specific to that user's language search.

**What is the data source for your Instant Answer? (Provide a link if possible)**
http://www.ineverylang.com

**Why did you choose this data source?**
I'm the developer, and there isn't another source with an easily consumable JSON format.

**Are there any other alternative (better) data sources?**
Rosetta Code has a ton of puzzle solutions, but I don't know that there is any easily-parsable way to get at that data.


**What are some example queries that trigger this Instant Answer?**
"Hello, World! in Java", "Fizz Buzz in Swift", "Binary Search in Erlang"


**Which communities will this Instant Answer be especially useful for? (gamers, book lovers, etc)**
Programmers, specifically ones that enjoy katas.


**Is this Instant Answer connected to a DuckDuckHack [Instant Answer idea](https://duck.co/ideas)?**


**Which existing Instant Answers will this one supersede/overlap with?**
SearchCode and CodeSearch


**Are you having any problems? Do you need our help with anything?**
I don't think so, unless there is something wrong with this PR!


**What are the terms of use for the API? Will DuckDuckGo need specific authorization (e.g. an API key)? Are there any costs associated with API usage?**
No costs or terms. InEveryLang is my project, and I'm sharing this with DDG fo free.


**Where did you hear about DuckDuckHack? (For first time contributors)**
