global config not reloading when new rules are added

[Victor Vrantchan]

Here we try to load a config by MachineID and if that fails, we use a cached global config

moroz/moroz/service.go

Line 65 in ece124d

 config = svc.global 

changing that line to config, _ = svc.repo.Config("global") would be a sufficient fix for now.

In the future we can look at fsnotify to reload configs.
