It seems that request#json is not a property (dict) but a method returning data (the dict wanted),
thus the parenthesis are needed (I got an error when trying to use this software the first time,
maybe related to the version of the dependencies).
Modified slightly EndomondoWorkout such as it stores the raw dict data earned
from the request to the server.
Added a little script displaying a list of all workouts with their raw data.
Add a .gitignore file and ignore byte-compiled *pyc files.
