I know we are going to change this later, but I think that `ramMax` can just be set to `this.blockly_allowedBlocks`, which means that this can reduce to:

    this.ram = this.blockly_allowedBlocks - this.blockly_blockCount;

Of course, if we are going to reference blockly properties inside the rover component, we need to make sure that the rover component implements the blockly behavior (not just from the app, but actually inside the component).  That will require us to move where the blockly driver stores the nodes from `creatingNode` to `createdNode` so it will correctly identify blockly nodes.
