Transform the DiveProfileItem to an Abstract Generalization

Browse source 
The DiveProfileItem contained much of the complexity and
algorithms for almost all line-based items on the canvas,
so I transformed that to a general abstraction and implemented
a new DiveProfileItem that uses it. this should reduce a
bit of code since the implementation of the PP Graphs, Temperature
Cylinder Pressure and maybe a few others will only need to
reimplement the paint() and the modelDataChanged() methods.
The rest is ready.
