Jump directly to result if only one match

!! This is almost functional. It just needs to be figured out how to wait for the ag buffer to finish updating.
Implemented using a new hook ag-post-search-hook.

This is a PR associated to this issue: https://github.com/Wilfred/ag.el/issues/89 Once I figure out how to solve that issue, I can update this PR to be fully functional.

Explanation for adding ag/last-search-buffer-name as seen in the PR. A user could have multiple ag buffers open. The above var makes sure that if the user has

(add-hook 'ag-post-search-hook #'ag/jump-to-result-if-only-one-match)

only the buffer for the last ag search that that only 1 match gets closed.

This does not need to be merged upstream. But this functionality can be achieved by the below AFTER PR https://github.com/Wilfred/ag.el/pull/92 is accepted:

   (defun ag/jump-to-result-if-only-one-match ()
      "Jump to the first ag result if that ag search came up with just one match."
      (let (only-one-match)
        (when (member "--stats" ag-arguments)
          (with-current-buffer ag/last-search-buffer-name
            (save-excursion
              (goto-char (point-min))
              (setq only-one-match (re-search-forward "^1 matches\\s-*$" nil :noerror))))
          (when only-one-match
            (next-error)
            (kill-buffer ag/last-search-buffer-name)))))
    (add-hook 'ag-search-finished-hook #'ag/jump-to-result-if-only-one-match)
