Updating Definition of Acre as 'state' rather than territory

[cathal444]

Fixes #533

-Rather than keep the old Synset for 'Acre' and create a new one, it seems more appropriate to update the existing definition and adjust the relations accordingly.

I am not sure about the final solution. I would think we lost information with this approach because in many texts Acre will be a territory... This is also related to #712. How can we keep track of changes in senses? I reasonable solution can be to just add new senses.

@cathal444 I think this is the wrong hypernym ewn-08185877-n is the synset for 'state, nation'. It should be ewn-08671935-n

@arademaker We still have the information that Acre is a territory as the synset for 'state' is a hyponym of the synset for 'territory'. A state is just a more specific kind of territory.

On the question of tracking changes of senses (this should probably be discussed in separate issue), OEWN is a dictionary of modern English and there are no plans to model diachronic changes in meaning. For factual, encyclopedic facts, I would say the best is to model the current situation.

Fine. We just need to be consistent. If that is the decision, maybe we can find other cases where two senses differ only by temporal use.

BTW, I didn't notice that territory is hyper of state. Thank you.
