HEAD
Starting to implement common header and color scheme for LON-CAPA handlers
(non-content pages).
Instead of <body bgcolor="#...."><h1>... call
&Apache::loncommon::bodytag(title,[role],[add_body_parms]);
title: what it says in the header
role (OPTIONAL): override role choice
('admin','coordinator','student','author')
add_body_parms: additional parameters to be put into the body tag, for
example 'onLoad="init();" or stuff
Colors and layout will likely change in the future, including domain
customization, help function calls, (css?)
