[gedit/wip/search-fixes: 2/2] Move code from gedit-commands-search to GeditReplaceDialog

[Sébastien Wilmet <swilmet src gnome org>]

commit 90149a5458b9fd5abd7c0dcefac8b787bcc37a28
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Sat Aug 24 22:50:08 2013 +0200

    Move code from gedit-commands-search to GeditReplaceDialog
    
    When the search and replace dialog is shown, get the buffer selection,
    and if the selection is small enough, place it in the search entry.
