Extend Boxes to support Ctools content.

I'm using Boxes to render Ctools content types that don't require a Ctools context. My plugins make allow Boxes to display nodes (any build mode) as a block, clone other blocks, and embed contact forms. It provides the same functionality as other modules:

• Block clone
• Node As Block
• Contact form blocks

But under one UI, API and with exportability.

In the current form, I had to make some compromises and hacks around form generation and validation. This is only the low hanging fruit. Handling more complex content types would require better knowledge of ctools forms than I have.

The real stuff happens here:

All of the other plugins are wrappers to pass in the name of a content type and to create a tab on the block admin page.

If this interests the maintainers, I'm happy to patch Boxes. Any advice or suggestions are appreciated.
