Users will first be shown the first 25 responses of a viewed thread and
then have the option of loading 100 more at a time until all responses
have been loaded. This mitigates the performance impact of very large
threads by avoiding the need to render and transfer over the network
all content of a large thread at once. It will also allow students with
slower browsers to interact with large threads even if they cannot load
all of the responses.

The relevant parameters and data are merely passed through between the
front end and comments service.

add "Add A Response" button to thread views in discussion tab / inline

Allow new response pagination parameters to pass through thread model.

append-only, and track the user who is making the change, and the time
that the change was made. The configuration is stored in the database,
and cached for performance.

Extend the capabilities of the REGISTRATION_OPTIONAL_FIELDS
configuration variable, to allow to select, for each individual field,
if it should be 'hidden', 'optional' or 'required'.

Rename the configuration variable to REGISTRATION_EXTRA_FIELDS to reflect
the additional capabilities, and updates the defaults.

As extra fields, configurable through the REGISTRATION_EXTRA_FIELDS
variable. Hidden by default.

Note: Studio also has a registration page, which uses the same account
creation page. It should be possible to use it without requiring the
variable from the LMS, as the fields are different.
