Unmaintained ElasticSearch Essentials 2.4.13

• Fix clicking on auto-complete results not doing anything
  
• When autocomplete returns no results, do not show "no search results" instead offer a search link for the auto-complete term.

Compatibility update for upcoming word count search update

• Do not error if "Browser Detection (Mobile/MSIE)" add-on is not installed

• Remove dependency on (unmaintained) "Browser Detection (Mobile/MSIE)" add-on for mobile detection
  • If this add-on is installed, it will be used instead of XF's built in mobile detection.

• Support specifying the ordering options for auto-complete
• Improve Enhanced Search Improvements integration, supporting the options "Log Search DSL" and "Content Type Weighting" options for auto-complete

• Fix error when searching for deleted content

• Autocomplete search will now silently strip wildcards, as this isn't supported and will most likely return hits that match it due to how the query executes.

• Do not throw "Please specify a search query or the name of a member" if there is some search criteria, and the search query is empty.
  • '*' is a valid search query which matches everything, so this error message was pointless.

• Restore compatibility with Elastic Search 1.x versions
• Add install check for Elastic Search version
  • Refuse to install on 0.x
  • Recommend updating on 1.x
• Add php version check (require php 5.4 or newer)

• Do not allow more than 1024 search terms, in default configuration this will cause Elastic Search to error. Verbosely.
