Feature/rails goes to config


This is a bugfix.

Aaron found a bug, a serious bug. Since we merged the dotnet support we are generating our files in the root directory of any app instead of config/

The main change is that now we have a  Project.config_dir which will select config/ or root depending on the type of app.
It now only support Rails vs non-Rails , the ideal would be to support dotNet vs non-dotNet, if you know how to detect dotnet projects please enlighten me.

We can also do something like if there is a 'config' directory then use it, else go for the root. I do not know if dotnet have some misleading 'config' directory though.
