true/false or TRUE/FALSE to prepare for the new boolean type and constants being added to Python. Added code to wx.py to test for the existence of the new constants and to create suitable values if not present. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/WX_2_4_BRANCH@19335 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
