Include missing templates

[stepmr]

These are missing and should probably be included in the repo.

• waitinglist/survey_invite_subject.txt
• waitinglist/survey_invite_body.txt
• waitinglist/survey.html
• waitinglist/thanks.html
• waitinglist/list_signup.html.html
• cohorts/cohort_list.html
• cohorts/cohort_create.html
• cohorts/cohort_detail.html

Hi is there anyone looking into this

[ossanna16]

@stepmr Are you interested in creating a PR for this? We'd appreciate it! :)

[stepmr]

@ossanna16 sure, I'll have some time at the end of the month to cleanup my implementation :)

@stepmr Thank you so much! 👍

let's put these templates into pinax-theme-bootstrap instead of this app. Templates by their very nature tend to have bias towards certain framework. Please put send your pull request with templates there.
