Coordinate-system names

The algorithm used to generate the names of coordinate systems has changed. This means that data coordinate system names which used to look like plot2_ax1ay2 now look like ds. Since they can no-longer be guessed from the plot and axis names, the info_coordinate or info_current commands should be used to find out the name.

Info ordering

The order that objects are listed by the info and info_current commands may be different for those objects that are "children" of plots (so curves, histograms, contours, images and the annotations).
