python - ip: Specify the tuple components (interfaces).

Log Message:
-----------
Specify the tuple components (interfaces).

Specifies the interface consistency of attributes, tuple descriptors(sequence of
attributes), and tuples("instances" of tuple descriptors).

Other minor corrections/improvements might have made it in as well.

Also, modify the xhtml stylesheet to use a lighter color for links, and set the
id attribute to the varlistentry's before its term.
