meddleware broken with config v.3.0

[fernandocanizo]

config package made its returned objects sealed on version 3.0. This breaks meddleware:

$ node maps.js 
/tmp/map-server/node_modules/meddleware/lib/util.js:50
    obj && (obj.name = name);
                     ^

TypeError: Cannot add property name, object is not extensible
    at nameObject (/tmp/map-server/node_modules/meddleware/lib/util.js:50:22)
    at /tmp/map-server/node_modules/meddleware/lib/util.js:38:16
    at Array.map (<anonymous>)
    at Object.mapValues (/tmp/map-server/node_modules/meddleware/lib/util.js:36:29)
    at Function.onmount (/tmp/map-server/node_modules/meddleware/index.js:196:14)
    at Object.onceWrapper (events.js:315:30)
    at emitOne (events.js:121:20)
    at Function.emit (events.js:211:7)
    at Function.<anonymous> (/tmp/map-server/node_modules/express/lib/application.js:238:8)
    at Array.forEach (<anonymous>)

There is a work around given on this config issue, however having immutable and sealed objects on require('config') is desirable.

Do you think meddleware can do something about it?
