Project descriptions

PEP8 corrections and refactoring will be done this week.
Changes:
Create project description generation in French, German and Italian.
Create project needs text pattern to fill.
The browse method will return an object if you pass one single id, or a list of objects if you pass a list of ids.
The param name (project_id) indicates that you're awaiting one single id. So, what is the purpose of this line ?
