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 code for this item is a bit too big to be just the grid
of the dives and I know that, don't bully me. :)
The main idea of this grid is that it knows when it should be
updated. this is a bit different than the old code where all
the painting happened on the same method. This is bad because
it's more code, but it's better because if I break the grid,
only the grid will be broken, and it's easyer to spot the breakage.
in the old code if I did the wrong thing with the graphics context,
the whole graph gots messed out.

Created a Time Axis based on the CartesianAxis that knows
how to plot the minutes. This is needed because the CartesianAxis
donesn't knows about minutes at all, and would plot the
seconds instead.

The CartesianAxis used a simple method to put things on screen
which is wrong for almost any case besides the 'current value here'
since we store things in milimeters on the axis, we need to convert those
to meters before showing on the profile.

This is the same class as the Ruler, but uses the DiveLineItem
and DiveTextItem classes created to make it animateable. The next
few commits will work on that part. The Ruler was a very bad
name for a class that's actually an Axis, that's why I depreceated
the later.
