graphs: all multisession graphs and rjEvolution now have a palette in
	constants.cs if palette is small for graph, then use random but values
	far from white

	graph rjEvolution now has different marker for tv and tc

	report: less cols for persons if not needed
	report: rjEvolution jumps data in rows

	fixed size in treeview persons

	fixed three noticeable bugs: (1) some bad code inherited from old use of
	"all/none" row in stats treeview, (2) some bad code for the old using
	"id: name" for comboPerson. These bugs make crash the rjEvolution
	report, and makes problems in some parts of the code if the jumper
	name has no ' ' (3) checkboxes in treeview stats doesn't add rows to
	markedRows without checking if that exists (and delete doesn't check
	if there is more than one of every row)

	fixed all warnings
