wxWidgets wizard problem

[manmach]

I just tried to create a new project with the wizard and ran into a (minor) problem.

The project is to test wxWidgets and SDL combined, so I called it wx-sdl.

Turns out, the wizard does not check validity of the names it generates, because I ended up with defines and class names based on wx-sdl, which contains a minus sign and that is not allowed in neither a define nor a class name.
