Profile: Change RulerItem2 to use index instead of pointer

To make the pressure data dynamic (size of the arrays depending
on the cylinders in the dive), it has to be separated from the
standard plot_data structure. To enable this, use indexes instead
of pointers to plot_data elements. This commit converts
the RulerItem2 to use an index.
