This makes the Gas Pressure Item a 'cached' item, when the dive
changes, the item will regenerate the drawing based on it's model.

This patch adds a new class DiveCalculatedTissue that's preferences aware.
It knows when to show or hide itself.

The reported ceiling now behaves better by not being deleted / recreated,
instead it uses the same object and connects to the model to know when to
regenerate its plot.

This patch makes the cartesian axis of the profile depth shrink and
(together with it) the Profile Depth and the grid lines. There will
probabla bey a lot of things that didn't have their correct position
fixed, so I'll fix them in the later commits.

Dirk's implementation of the MeanDepth item was correct, but in order to
add the 2 strings to it ( one at the begin, one at the end ) I had to put
more stuff inside the ProfileWidget that's already packed with graphics
items.
So I created a new class MeanDepthItem that contains these 2 strings and
will get updated whenever the value changes.
I also fixed a math inconsistency where I changed RIGHT to LEFT.
(wich fixed a few text-placements, and broke others.)

When the preferences changed signal is fired, the items that can change
their visual based on the preferences now have to reimplement the
preferencesChanged method, so they know if they need to be replotted on
screen. I already implemented that for two of the items ( ProfileDepth and
Ceiling ) but others might need that too.

This code actually uses the preferences for something. It will show and
hide the calculated ceiling in red if the prefrerences are changed for
that. One bad thing that I did in this commit ( so it was easy to try ) is
that a preference change will redraw the whole graph - not optimized. I'll
make this better in a later commit so that only the affected items will be
redrawn.

This is an attempt to speed up painting a bit. Since we will draw the red
ceiling on top of the profile, I don't see a reason to dig a hole in it,
creating an more complex shape to be passed to the painter. Easier shapes
are easier to draw. ( I think )

This patch adds dive computer calculated ceiling on the profile graph as a
'hole' on it. There's an item that paints it in red - maybe we shouldn't
offer an option here and show that only in red?

This just adds the texts for the gas profile. I've also added a method on
the dataModel() to return the diveId of the last used dive in a way that
the other methods can use it.
This code is almost 1-to-1 with the old one, a bit of thinkering can be
used to merge this loop with the upper one.

Removed the plotText function and replaced it with the

text on screen, and it also makes it easy to fix positioning

I Moved the 'plot text' method of the Old Graphics to the new
layout - this one was mostly unchanged as it was already good
as is.
And used the TemperatureProfileItem to also display texts.
This was the first implementation of the new system that uses
*less* code than the original one, wich makes me happy.

Added the Temperature Graph with its related classes. A Temperature Axis
is also created so the item is plotted on the right place.
Currently the Temperature Axis is just like the depth axis - top is
zero, wich means that the graph is inverted.
Also, the Temperature axis is being displayed as this helps debugging.

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.

I've used the paint() method on it ( even if it's not necessary
on a QGraphicsView ) to reduce absurdely the number of items that are
inserted on the QGraphicsScene ( each small line of the profile should
be an item if it was not for this, it's like that on the old profile. )
and thus reducing the memory consumption, speed and so on.
