Activities getting appended if page is not reloaded between ride sessions

[dvmarinoff]

The only way to clear the current riding session is to click stop, and reload the page or download the current activity.
This behavior was needed to ensure that data is not getting lost before the workout file was downloaded even if it is stopped.
But this causes the issue where 2 activities might get appended to each other if the browser page is not reloaded between rides.

Now activities are saved in the activity list, when the stop button is pressed. So this might no longer be needed.
The user can download the activity from the list or sync it to remote services. So maybe even the download button in the main menu is not needed anymore.
