Cross-wiki Search Result Improvements/explore similar

What?

 * Upon arriving at the search result page after querying Wikipedia, there will be additional information displayed containing article page links, categories, and languages that the article can also be read in.

Where?

 * The links will be displayed within a box-like content area that can be expanded by hovering (or clicking) a link that is specific to each search result returned.

How?

 * Logged in users can test this new functionality by editing (or creating) a common.js file - more information can be found in the self-guided testing page.

Why?

 * We want to find out if adding related information to the search results will aid users with additional rich data that is useful in the context of the search query the user inputted.

Can I help?

 * Yes, please!
 * Update your common.js file in your logged-in profile and try out the functionality and let us know what you think of the results. Are they interesting and/or useful; do they help with your research or editing needs; do they pique your curiosity about information related to your original search query? Feel free to add questions and constructive comments in the talk page.
