Update textproc/the_silver_searcher to 2.0.0

Changes:
2.0.0
-----
- Remove support for `.agignore' file, please use `.ignore' instead
- Add --print-all-files option.
  This option causes ag to print headings for all files that it
  searches, not just those that contain matches. This will be useful
  in the case where ag is being called by another program that needs
  to show the user a progress indicator of how many paths have been
  searched.
- Add Haxe support
- Add support for jsp tag and fragment files
