Event Streams WD02 PR

https://github.com/oasis-tcs/amqp-specs/pull/9 The model of having a document per draft version doesn’t work all that well now that we have proper version control, so I put the changes on top of the -wd01 file for review.
I suggest we change the model for these files such that we increment the number with each PR in the document, but omit the numbering from the file name.
If you need an earlier version, you go into the history.
