Apply selection of JEID's modsupport mixins on dedicated server

JEID's modsupport mixins are all specified as client side only - indeed JEID by default does not even apply it's loader mixin.
This doesn't make sense as a lot of these mixins apply to server side only code and should be applied on both client (for SP) and server.
