move logger and config_data to func/func

update modules that need new location

modules/func_module.py: update to use new logger/config locations,
	also go ahead and register as a real module, to shut up the
	start up. It shouldn't hurt anything

Some minor import reordering at a couple places (I try to keep
at least system import alphabetical)
