Beanwriter is creating compounds that extend HippoDocument

I noticed that the beanwriter is generating beans for compounds that extend HippoDocument, not HippoCompound.

I think this is wrong, compounds should not have access to methods relating to translation and workflow. I recall when HippoCompound was introduced, it was intended as a base class for compounds instead of HippoDocument.

Reproduction:

1. Create an archetype 11 (or older) project
2. Create a new compound type
3. Run the beanwriter tool

expected: a bean class that extends HippoCompound

observed: a bean class that extends HippoDocument
