Message:

Show a capture of the workout map, as an image, in the dashboard:

• Added a view to render the tracking map of a workout full screen

• Added a small shell script that uses chrome to grabs a screenshot of the full screen map view of a workout, then uses imagemagick convert to crop/resize it and finally saves it in a given location

• Added a static/maps directory to store maps captures

• Added static/maps to the boring/ignore file

• Added a tool in utilities.py to call the shell script that captures the screenshot of the map

• Added a method to the Workout model, that returns the static path to the workout map capture (valid to use with request.static_url()). If there is no capture yet, call the tool to make one

• Added code to dashboard.pt to show the capture of the map

• Added a new parameter to te ow maps js code, allowing us to hide/show the zoom controls of the map when building a new one
