microgateway-config dependency

[philschleier]

I've noticed that microgateway-core depends on microgateway-config, although it's not used.
During the 3.1.3 update, the version for microgateway-core was changed, but the dependency (npm-shrinkwrap) not updated.
Now, when installing edgemicro, I have two different versions of microgateway-config.

Can the dependency be removed from this repo? (The differing versions lead to a problem elsewhere for me)

EDIT: Got my edgemicro/microgateways all mixed up ;-)
