[visionegg] upgrading code to work with 0.99...

Hi Andrew,

I'm upgrading my code to work with 0.99, and I've played around with this
error for a while now, and I'm stumped.

I suspect I fell afoul of the new type check system, but you'll probably see
immediately what needs to be changed to make this code 0.99 compliant:

handle_evenhandle_event_callbacks = [(pygame.locals.QUIT, quit),
                          (pygame.locals.MOUSEBUTTONDOWN,
button_down.click),
                          (pygame.locals.MOUSEBUTTONUP, mouse_button_up),
                          (pygame.locals.KEYDOWN, keydown),
                          (pygame.locals.KEYUP, keyup)]

setup = Presentation(go_duration=('forever',), viewports=[viewportforsetup,
left_mask, bracketviewport], handle_event_callbacks=handle_event_callbacks)

The error message I get is as below:

Traceback (most recent call last):

type <type 'list'> (not type Sequence of Sequence2 of AnyOf(Integer or
Callable)) in <VisionEgg.FlowControl.Presentation object at 0x27aea08>

As always, thanks so much for your help!
