make sure we can only init DE once. This block of code will eventually be used to init DE whereever we do so (valuedump, etc) - keep in mind that the other questor tools will need a bit more work as we either need to make sure they are launched from questor (2nd instance of DE w/o cloaking) or not launched from questor (1st instance for DE with cloaking) and that bit is going to get complex I fear =(
