Infrastructure

Minor release with upgrades to Mercury.

The changes include:

• One "SEARCH" button on the search page

• Removing the ranking stars on the results page

• Sorting by Relevance (default), Start Date, and Most Recent
  Enabling sort by title, author would require some internal changes that will take a fair bit of effort, the problem being lack of normalization of author names, and the way the indexer is processing title text.

• Layout of results is a bit more like a citation, with Author, Date, Title

• Forced upper case of the title line in search results is removed

• Identifier of the object is listed under the citation row

• The data package view (when clicking on Data Files button) shows content indented a little under the package

• The COINs tag generation for Zotero and Mendeley import is significantly improved, and now operates consistently across those products
