JBIDE-16593 - updating launch args for soa 5.3

Closest I could do is something like JBossServerType.EAP_STD.getId(),  but that would be misleading because several server bean types might actually have the same id due to legacy behavior from when I first copied this from... um... installer? Not even sure.   The strings themselves are not stored in constants anywhere.  For example about 6 bean types have an id of "AS".
