Added a ruler which can be dragged along the profile

Browse source 
This patch adds a ruler QGraphicsItem which can be dragged
along the profile. The ruler displays minimum, maximum and
average for depth and speed (ascent/descent rate). Also, all used
gas will be displayed.

This also adds a new attribute to struct plot_data to store the
speed (not just as velocity_t).
