[Plugin: Term Menu Order] Deactivating the plugin should not remove the menu_order data

In NS_TMO_Plugin->deactivate(), the column “menu_order” gets dropped from the terms table. This means all this data gets thrown away and you need to start over upon reactivation. Shouldn’t it be better to only remove this data when the plugin gets uninstalled?
