Feature waiver

[wengf2086]

Really sorry about having all these changes in a single commit. I didn't want to risk accidentally committing the environment file again, and I wasn't sure if Robert's changes for the new environment.org.ts file were working and I didn't want to break my code. This isn't how I usually work, I promise I won't do it again!

• Added waiver to ChangeMaker registration process (user must sign waiver to register as a ChangeMaker)
• Added boolean field 'hasSignedWaiver' (default: false) to ChangeMaker entity, model, interface, dto, createProfile, user query
• Upon registration, 'hasSignedWaiver' is set to True
• Project-specific waiver has been replaced with generalized waiver (same as the one that appears during registration)
• I've saved the template for the project-specific waiver in case we ever need it again.

When signing up for a project:

• If the user has signed the general waiver, the waiver will already be accepted and they just need to click submit.
• If there is a custom waiver, they will only have to review and accept that
  -If the user has NOT signed the general waiver, (they registered as a CM before this change was made), they will have to sign the waiver at project sign-up. After submitting their application, hasSignedWaiver will be set to true. In the future they will not have to sign the waiver again
