This change brings nearly all copy and paste related into a single, self-contained class. This new class is still somewhat coupled to CPPlatformWindow+DOM.j in the sense that it's highly specific and meant to be called in a very specialised way. Despite this, it's still a significant decoupling and the new code is more readable and easier to follow.
Image copy and paste to and from the system clipboard is not available in Cappuccino today. However, the image in the collection view can be used to test internal Cappuccino copy and paste (using Edit > Copy, Edit > Paste from the Cappuccino menu).
This test makes it easy to test copy and paste both inside a Cappuccino app, and externally to and from other Cappuccino instances in other browser, or other applications, when using a text field or a collection view as the source/destination.
