clean up the article system

[n-aspen]

make the styles for articles and content boxes more streamlined. as an example, use classes to change the appearance of a n article while still having the original and sub styles of the article. such as changing the background color or changing how lists and or links are displayed.

changed the box system so that the default scheme can be overridden by using a style class.

progress is being made on cleaning up the way styles are defined and in the way they are placed on elements. i've created a test page that explains each style and what classes are required to get it on this page https://mov51.net/test.php
