Define a partial template which can’t be used directly

[brendanheywood]

More or less like any other template except these will be marked somehow so they don’t appear in the activity chooser and perhaps their inputs can be declared at author. These then become available to other real templates as a partial you you can easily share common bits in one place

This should use the BLOCKS pragma feature here:
