FULLPIPE: Implement sceneHandler09_winArcade()
FULLPIPE: More initializations in scene09
IPHONE: Don't link against private framework GraphicsServices.

Nothing from that framework in specific is used, thus it's not required to
link against it.
AVALANCHE: Use keycodes instead of ASCII values in Help.
AVALANCHE: Simplify continueHelp(), move keyboard control to it's own function.
AVALANCHE: Implement mouse control in Help.
AVALANCHE: Get rid of continueHelp(), fix run().

It was unnecessary to paint the whole screen black, we can just draw the
first screen of Help immediately instead of that.
AVALANCHE: Don't use cctype in Help anymore.
