Moved scripts to the root directory, and moved cfg to cfg.example.

The motivations are as follows:

* Having the actual code in the root directory allows the user to clone the project directly into the ES-folder and making the config file. That way there's no need to copy any folders, updating is a simple matter of git pull.

* In order to prevent the site specific config file to be over written on git pull, or sensitive information being leaked by an accidental commit of the cfg file, making a difference between the repo example and the site conf is necessary. This is common practice.

I hope you will find these modifications agreeable.
