Plot of the Cylinder Pressure over time.

Browse source 
a few code was moved around, a macro that contained
the form of x ? : y; had to be rewritten to x ? x : y
since c++ doesn't allow ternarys without the middle operator.

The color-choosing for the Cylinder Pressure broke
on the Qt port - but it's a small issue.
I'm painting everyone as 'dark green' now, will
fix that later.
