A demo app for Qt 4.6

The webscraps demo application lets you cut out segments of webpages
and keep track of them. Each scrap behaves like the actual website,
and also automatically refreshes itself periodically.

Some of the features that this demo uses are new in Qt 4.6: The
Animation Framework handles how the scene changes between the viewing
and creation of scraps, and Graphics Effects are used for
highlighting scraps. A state machine manages many of the animations
and effects.
