Berthold Stoeger 64b82b16a2 statistics: make selection keyboard modifiers more general
Up to now, we passed a "shiftPressed" flag to the individual
selection functions. To be more general replace by a struct
with "shift" and "ctrl" flags.

While doing this:
1) Move the struct into a new statsselection file for better
   encapsulation.
2) Change shift to control in the scatter series, since individual
   selection of items is usually done with control, not shift.
   Shift usually means "select range".
