Refinement of previous check-in re OOo transformations.

Browse Source 
I have pulled up the code that handles blocked transformations into a superclass so that the JodConverter-based transformer worker can inherit the same list of blocked transformations. To reiterate, blocked transformations are those that the OOo integration code believes should work but which are broken in practice. These are blocked by the transformers and will always be unavailable regardless of the OOo connection state.
