rint() is "round to nearest integer", and does a better job than +0.5
(followed by the implicit truncation inherent in integer casting). We
already used 'rint()' for values that could be negative (where +0.5 is
actively wrong), let's just make it consistent.
Of course, as is usual for the messy C math functions, it depends on the
current rounding mode. But the default round-to-nearest is what we want
and use, and the functions that explicitly always round to nearest
aren't standard enough to worry about.

SAC should be calculated in relationship to surface pressure, not "1 bar".
I also realize that we have a few other cases where we do the same
mistake: the partial pressure calculations do things like
po2 = o2 / 1000.0 * depth_to_mbar(sample->depth.mm, dive);
which is wrong as well - the partial pressure is also relative to
standard atmospheric pressures.

Created a method to check if calculations should take place
taking into consideration what changed on the model. if the
model changes *everything*, them, all calculations should
be done, but if just some of the columns of the model are
changed, only those columns should trigger an visual update
on the items.
In theory this patch looks right, but something is wrong (
calculations are not being made. ), so I'll commit this any
how, and fix on the next commit.

This commit is rather big, and I forgot to cut it in pieces.
The first part creates a new 'calculate_gas_information' that will not
fill the profile_info->maxpp member ( that should be removed from it as
soon as the new dialog is finished ). The reason for that is that all of
the profile data will be calculated and the graph needs to update
dynamically, so whenever the settings changes, I ask for the model which
is the biggest graph and replot only the ones we need.
The second part adds a new animation function 'animdelete' to fade-out and
delete the item when it's done. the old function 'hide' did just that but
a hide shouldn't delete anything.
The third part is preferenes awareness for the PP graphs. I created two
new functions that receive the settings key for visibility and use the
QSettings to show / hide them. This also works quite well for the axis;
if no graph is visible, the axis will also hide itself.
The fourth part is colors. The pp graphs now have the correct colors.
And a bit of code cleanup too.

The small straight parts at the end of tank pressure lines are more of a
aesthetic issue, not causing real harm so it is no reason to remove the
SURFACE_THRESHOLD test from pressure_time function only because of this.
Also improved interpolate data debuging, rearranged
get_pr_interpolate_data and removed an unused variable from
get_pr_interpolate_data. No real change here, just trying to make the code
clearer.

Interpolated lines for tank pressures were presenting discontinuities
(sudden drops) and stalls (horizontal lines) with certain dive profiles.
The main reason seems to be that the discrete interpolation of tank
pressure was adding small pressure increments that could be rounded down
or up repeatedly generating cumulative rounding errors that would mean
either a delay on pressure drop that would be drawn as a sudden drop or as
a premature pressure drop that would result in a flat line.
This patch changes the way the discrete interpolation is done, so that we
don't have cumulative rounding errors distorting tank pressure lines.
To calculate accumulated pressure_time values the get_pr_interpolate_data
function was created. The fact that get_pr_interpolate_data transverses
the beginning of the plot_info entry list for each entry that needs
interpolated tank pressure isn't optimal at all. There might be a way to
properly track the data necessary to interpolate tank pressures from
inside the main pi->entry loop in fill_missing_tank_pressures.
Unfortunately I didn't manage to do it inside fill_missing_tank_pressures
so we have get_pr_interpolate_data.
The SURFACE_THRESHOLD test from pressure_time function was also removed as
no matter how shallow the diver is, if he is using the cylinder to breathe
the cylinders tank pressure should be affected.

This also gets rid if the ccrdive state variable, and keeps that state
in the plot_data struct. Now we calculate the deco before we calculate
