v1.6.0

Features

• feat(books): added the bookshelf to the bottom of each book preview page.
• feat(search): added a button to clear all selections. Needed to return to filtering mode when coming from an entity clicked on the viewer webpage.
• feat(search): person info box can link back to the searhc page. Fixed the a:focus style.

Fixes

• fix(search): /entities/?hi=ppl:xb1 would return ppl:xb12, 13, ... Fixed this by removing the id from the search field in the index and filtering the id field by exact match on the value of the hi param in the query string.
• fix(books): the link to the viewer is now absolute..
• fix(viewer): improved positioning of the popovers. Also avoided gap the mouse pointer would fall off when the user moved it inside the popover. This used to cause the popover to disappear and the links it contained to never be clickable.
• fix(viewer2): the bracket on last three lines of R.177 (SD) was missing. Caused by the deletion of a previous CSS rule when we transferred the stylesheet to the new viewer earlier this year. Not sure why it was deleted.
• fix(viewer2): corrected the book names & years in the new viewer citation box.
• fix(viewer2): avoid using spread operator to improve js/browser backward compatibility.
• fix(viewer2): added correct citations for remaining three books.
• fix: close drawer button to appear on all pages (Safari)
• fix(static): removed the duplicate Description heading on the book one page.
