Note:
-------
I only got to a few of these items before code freeze for 2.6 - namely the one addressed in

http://bugs.sakaiproject.org/jira/browse/SAK-12991

so for clarity am editing this one to remove mention of SAK-12991 and re-targeting it for 2.7

----------------------------------------------------------------------

Update skins so that we can use better, more meaningful, more specific markup. This will be a two step task:

a ) update stylesheets
b ) update markup producing elements

 
 - turn breadcrumbs into lists
 - turn item action links (links associates with list items in a table say) into lists
 - get specialized with table renderings (flat, hierarchical, formish, metadata, etc.)
 - address text block rendering - craft a rich taxonomy of text block display and change markup to take advantage.

step (a) will not interfere with tool rendering. When (a) is complete tools can start to be modified to take advantage of it.
