Fix to build wxsDateTimePickerCtrl on Linux

[Bug Killer]

wxsDateTimePickerCtrl is excluded from build on Linux because wxsTimePickerCtrl.h refers to a misspelled include.

Fix :

replace #include <wxWidgets/wxsWidget.h>

with #include <wxwidgets/wxswidget.h>

wxSmithContribItems/Makefile.am must be modified to build wxsDateTimePickerCtrl.
