Title: Add a permanent block control above blocks.

Only create a default block type if it's specified. Create a permanent block control at the top of the instance that can create blocks and can accept blocks dropped onto it. Refactor the Sass to use ems instead of hard coded pixel values everywhere. Stop using heights for block controls and switch to just letting it be handled by positioning.
