EAttachmentHandler predates EExtension, so this is really just a code cleanup to use the extension framework. But this also demonstrates that extensions can target interfaces as well as instantiable types, since EAttachmentView is an interface. What's also nice is EAttachmentView no longer has to directly interact with attachment handlers. Instead of EAttachmentView having to query each attachment handler for drag-and-drop info, each handler now pushes its own drag-and-drop info to its EAttachmentView during initialization.
