10: Adding SMS and eMail functionality to ourLora.

I return to the firebase cloud function to add SMS and Email capabilities. These will be used based on the triggerAction setting for a IOT trigger. I show the setup of supporting Twilio and Gmail services and use to the Twilio and nodemailer libraries.

02:36 UI changes to support SMS messaging (SMS phone on user and SMS trigger action added)
03:22 Sign up for a free Twilio account to use their SMS service. Note: the free service will have a “Sent from Twilio free account” on all the SMSs but that is ok for my personal use. Once signed, in also request a Twilio phone number , its needed for sending SMSs.
