Add fields to the user profile page

[MitMaro]

Add the ability for therapist to edit the following fields:

• Their Certificate of Conduct
• ABA Course
• Gender (Change wording from sex to gender #63)
• Password

So this will essentially look and contain the same functionality as the registration form? Currently there are two separate forms -- one RegisterForm and one ProfileEditForm -- should we just merge the forms together.

Task list for this issue (which I assigned to myself).

Both parents and therapists should be able to edit their:

• Display name
• Email address
• Phone number
• Postal code

Therapists alone should be able to edit their:

• ABA training course status (completed or not)
• Certificate of Conduct status (whether they have it or not)
• Date of Certificate of Conduct receipt

I don't really think gender needs to be editable, and that there should be a different form for password changes. The password change form could be a new page, or just a different part of the same page, but I think we need to make it super-clear that users are changing their login creds.
