infinite recursion when grammar contains a class named "Link"

[gimoh]

When the grammar (i.e. application.wadl/xsd0.xsd) contains a class named "link" displayResult will enter infinite recursion when adding "active_schema_link" class. This is because the class name generated for schema for "link" class is "schema_link" which is the same as the internal class name used for anchors linking to result schema.
