Subject: [PATCH] Fix bug #2213 (part 5): GuiChanges lacks "Previous Change"
 button.

Make sure we jump to the next or previous change when we switch search direction. Without this patch, the same Change will be found and only the cursor is moved from the end (or begin) to the begin (or end) of the selection.
