Printing improvements: GetPageInfo() gets called after the DC has

been set and after OnPreparePrinting() has been called so it can
report the number of pages accurately; doesn't try to set
number of pages in print dialog, in common with other Windows apps;
wxHTML easy printing's preview shows number of pages
correctly; preview scrollbars are set correctly; keyboard navigation
improved
