Add 2 Auto-update flags to Easymorph config file

Today if the user prefers to be on Auto-update OFF, he has to change it every time he opens Easymorph, because it’s ON by default, as well as Auto-update in the query editor. It would be good to have 2 properties in the Easymorph config file to store the value ON/OFF of both Auto-update the user set.
