Early alpha of Slides, needs some testing

[tom66]

This is an early, early alpha of Slides, a presentation program. You can now scroll with your scroll wheel and move objects around.

Known bugs:
- When selecting multiple objects, click-dragging on another object doesn't work and selects only that object.
- Scrollbar doesn't update when viewport position changes.

Any suggestions appreciated!

I can't help very much, but it looks good. A must-have feature I suggest is export as PDF, so we can display Slides presentations in Windows (I always do that with OpenOffice).
