Merge lp:~aacid/unity/do_not_reuse_menus_on_order_change_for_5 into lp:unity/5.0

[Albert Astals Cid]

Do not reuse the menu entries if their order changes

Since the indicators api only have "add" and "remove" signals, if we reuse an entry that is not in the correct order it will case the menus or whatever this indicator represents to be in the wrong order
