SetSelection must not send an event. Fixed an off

by one index, and a crash (probably a Motif bug).
  Improved wxSpinButton appearance.
  Fixed some build warnings here and there in the samples,
removed use of deprecated wxList methods in prntdlgg.cpp, fixed
aot-of-range ID in tipdlg.cpp, fixed some errors detected by
valgrind.
