Glossary Added to the Draft

Hello everyone,

I just converted the glossary and added it to the draft:

http://w3c.github.io/alreq/#glossary

These are priority 1 and 2 terms. There are couple of entries missing. We
can keep working on the glossary in the Google Sheet and convert as we
progress.

We can discuss about other related topics tomorrow.

Best regards,
Shervin
