As a WWT user, I want to be able to view revision and contributor details associated with a particular word, so that I can learn more about the contribution and contributor.
**Acceptance Criteria:**
* When WWT is activated, disable all links in the content area.
* When a WWT user clicks on a word, a pop-up should appear.
* The pop-up should display the following information: username of contributor (with standard "talk" and "contribs" links), timestamp of contribution, and percentage of page written by the user
* The written format of the data should be displayed as follows: "username (talk | contribs), added this on [timestamp]. They have written [percentage]% of the page."
* The pop-up disappears when user clicks on any other word or part of the page.
**Visual Examples: **
* Note #1: For the visual specifications, you may refer to the CSS provided in the [[ https://app.zeplin.io/project/5d2de5983e2b55639c8730d0/screen/5d2efe79aa8fd44f2b02adca | Zeplin project link ]]. You can click on a particular element of the page to see detailed CSS info. Note that we will not be adding the edit summary information in this ticket.
* Note #2: This ticket does not include the edit summary. The work to incorporate the edit summary into the pop-up is included in a separate ticket: [[ https://phabricator.wikimedia.org/T228941 | T228941 ]]
