edx.org - reduces padding on course listing register buttons (all states) and resets box-sizing to border box to make a proper box model for element

Remove edX news from dashboard if marketing site is enabled

Return 404 for course about pages if the marketing site is enabled

When an unauthenticated user clicks the registration button for a course, they
are redirected to the registration page with query params that are ultimately
included in the form that gets submitted so they can be enrolled in the course
upon successful registration. The header login button is fixed to pass the same
query parameters to the login page so the user can be enrolled in the course
upon successful login.

It would be better to redirect to the marketing site course about pages, but
the URLs for those are not easily computed, and we do not have time to set up
a full mapping in the LMS config.

studio - alerts: synced up styles and sample markup

They are currently using a CA that is not installed on our servers. Since it
isn't a top-tier CA and we aren't submitting anything particularly sensitive
anyway, we don't have to feel too bad about this.

studio - alerts: synced up example HTML to show advanced settings live notification, aria roles, and action classes; integrated typography mixins

Pass through the value (either default or inherited) that a metadata field WILL have if it is not explicitly set.

The MKTG_URLS dictionary is overwritten completely in aws.py anyway, and we
shouldn't be trying to keep both the production config and LMS code in sync
with changes to the marketing site.
