sending messages wip
fix typos in return
fix typo, change creation of Message obj
calling the sendMessage function works
change to logging when user found/not found
create a pending message if user not found/not verified their email
sendMessage cloud function now also looks up a user by fbid, queues a Message if user found else queues a PendingMessage'
if a user links their account with FB later, need to use the masterkey to be able to update that row
send push notification to toUser of a queued message, fixes #3
Merge pull request #6 from cat-chat/sending-messages
