[IMPROVEMENT] Add capability to load multiple settings file

[ricardovsilva]

I have the idea to add capability to classifier load multiple settings file.
For example, I could create dotnet-developer.settings for dotnet files, then, when I run classifier, it will classify also dotnet files. Something like .gitignore, but for classifier.

Sure. Although, let me first test the current version of classifier completely, and update it on PyPi.
Then we could discuss on further improvements.
