Title: Disable preMerge if false is specified

I might have misunderstood this feature, but it seems rather confusing. After you carefully collect configuration from all those files, the data object would replace colliding names. Seems to me like potential headache approach. This workaround seems rather silly :)

preMerge: (config, data) ->
delete data[key] for key in Object.keys(data)
