Added email functionality to Create Game
Added mailer creation and email sending to the Create Game button.  It still sends to the team email via MailTrap.

For the demo, we would need to show the MailTrap account.  Here's the login info:
email: struct-by-lightning@gmail.com
password: team6password

Just go to Mailtrap.io and login, then select the inbox that already exists. Then refresh once you think the email has been sent to see if it's shown up.

Save list of requirements based on what the user selects
Fix so that the saved requirements are the ones the user selected, instead of the ones that the user didn't select.

In the function that grabbed the requirements and saved it to a list, the function now grabs the user selected requirements, instead of the ones that the user didn't select.
