Make the "id" parameter for the signup block a block setting

Okay I found it down the code for Billwerk:

It's the $planVariantId!

Here's the code being called in BillwerkApi:

  /**
   * Retrieves the URL for a signup page for the plan variant id.
   *
   * @param $planVariantId
   *   The ID of the plan variant to get the signup form url for.
   *
   * @return mixed
   *   The retrieved signup form url or FALSE.
   */
  public function getUrlSignup($planVariantId) {
    return $this->serviceUrl("portal/signup.html#/$planVariantId", 'selfservice');
  }

I think this should better not be a URL parameter but a setting of the Signup Block. Otherwise the user will be able to modify the ID in the URL and register for any $planVariantId, which is typically not what you want and kind of risky.

With a setting, the ID can be set in the block and you can place blocks per ID. Id anyone needs a more flexible solution, the setting can be modified in hooks.

As the module is still alpha and no existing installation is shown on the module page, I implemented this as breaking change!
