Probably messed this up :) This script was the only user of the tab-div
etc global CSS, using it for tabbed navigation. I've modified it to use
the standard navigation CSS, but haven't tested it because it's unsupported
and despite some tries I couldn't get it to work correctly (missing columns
in the data model among other things). I'm not sure that Lars Pind ever
finished this, or if only an unfinished version got committed, or if the
unfinished part wasn't needed by his client, or what. However, the package
is unsupported and requires the unsupported contrib package bcms so I'm
not going to loose too much sleep over whether or not my css change works.
