Helen Hou-Sandí dd08157024 Notices: Add styles for use against white backgrounds.
These colored backgrounds can be accessed by adding the `.notice-alt` class to a notice.

There is also now a large version when using the `.notice-large` class, and a `.notice-title` class that is appropriate for headline text within a large notice.
