issue #319. We now send emails to advisors once they register using the send_mail method provided by django.

In python, there is implied continuity for adjacent string literals, so you don't have to use the slash:
```python
send_mail(
    'BMUN 63 Registration Confirmation',
    'You have officially registered for BMUN 63. To '
    'access your account, please log in at huxley.bmun.org.\n\n'
    'The school registration fee...`,
    'no-reply@bmun.org',
    [...],
)
```

Not that there are no commas after some of the lines. For those lines, the string literals are adjacent, so they're considered part of the same string.
