Add develop and production mode in setup.py to origami-lib

As of now in origami there is only one setup and for testing and development puposes user have to manually install certain dependencies. It would be much better if we can give user a `develop` install for origami-lib which user can use for development and testing puposes.

I'm still digging the best way we can have here but I am thinking something on the lines of https://github.com/owtf/owtf/blob/develop/setup.py

What do you think about this @AvaisP @uttu357 ?
