Added functionality to select a dive to be shown in the T3 profile view: The new T3 Profile provides the option to display the profile of a previous dive which is stored in the log. This may be done by using the <enter> (middle) button. In case the dive is selected for the replay function a '>' will be shown in the lower right corner.
