Up to [LON-CAPA] / loncom / interface

Conversion of role names now occurs in lonnet::plaintext().  If rolename is set for a specific role in the course environment this is used, otherwise defaults to name defined in rolesplain.tab.  rolesplain.tab can now contain multiple entries (: separated) - which one is used depends on course type. loncommon::course_type() is accesssor function added to provide type; loncommon::convert_role() eliminated.  loncommon::bodytag() now includes $realm information for co-author role.
