Mgmt command for boarding pass mailout

Slowly but surely sends boarding passes out.

Has template for html and txt sepearte so we can try to direct users to
HTML to get the base64 image.

We may consider adding the image as an attachment as well as the in-line
to allow it to be opened in plain-text emails, but I don't know if
that's desired.

Just a base, templates will need to be spell checked and spruced up
before sendout. But this will provide the tool to send the boarding
pass out.

Now we need a UI for front-desk to use.

 This is the plain text version of your boarding pass for linux.conf.au 2018.
 The HTML version of this email has a QR Code embedded in it, and it would be greatly appricated if you could switch to that version to print or bring on a phone for check in so we may use the QR code to check you in.
 In the event this cannot be facilitated, please provide the following backup code.
 Backup Code: {{ access_code }}
