[tei-council] Release Notes

I will XMLify and commit the release notes at https://docs.google.com/document/d/1U1z6eCbJKVmu8k1KWB4ht6qqZxcTXXycKaVYqzho... later this weekend (maybe this evening, more likely tomorrow). Please look them over and make any changes you think necessary before then. Thanks, Hugh
