1. wxWizard appears in the centre of the screen by default

2. the selected brush isn't damaged any more by DrawBitmap()
3. corrected confusion between current and bg brush in DrawBitmap()
4. added wxGetColourFromUser() (to match wxGetTextFromUser() &c)
5. mem leak/crash in wxListCtrl on mode change fixed
6. wxListCtrl::Set{Fore|Back}groundColour() work as expected now
