we've determined that it's a pita to recreate the old behavior, so we're moving to using spans & classes.   we enabled classes that begin with  w-  to be passed throught the html filtering.  

To use this we'll need to make the following changes on cp:

1. modify local.css to apply to   .w-spotlight & .w-highlight,
2. configure *tinyMCE.  add
   
   • theme_advanced_styles : "spotlight=w-spotlight;highlight=w-highlight"
   • 'styleselect' to the appropriate spot in 'theme_advanced_buttons1'
   • add '/stylesheets/local.css' to content_css:

And we'll need to create a migration for the existing data.
