Title: Added some generic message classes to the style sheet

class="notice" for a general-purpose attention-getting note (yellow background, tan border)
class="notice success" for a success message (light blue/green background, darker blue/green border)
class="notice error" for error messages (yellow background, reddish border)

We can tweak as needed once we see them in situ. Error messages might warrant a thicker border, for instance.
