Fixing tab order in open dialogs.

Fixing tab order in open dialogs.

This CL prevents from loosing focus "between" elements. But focus still may be lost after last focusable item (it's a different issue not fixed here).

BUG=chromium-os:29056
TEST=Open open and save dialogs. Check the tab order is following 1) File list (initialy focused in the open dialog), 2) File name box (initially focused in the save dialog, absends in the open dialog), 3) Open/Save button, 4) Cancel button.
