TAP5-1659: PageLink: page parameter should accept page-classes and
page-instances
FIXED - TAP5-2214: Make tapestry5 java8 compatible 
- apply source from AMS 5.0 final source release and change package name
to org.apache.tapestry5.internal.plastic.asm. Also made a single change
to ASM source, promoted visibility of AnnotationNode.accept from package
private to public so I didn't have change to plastic (to instantiate
AnnotationNode)
TAP5-2300: JavaScriptSupport.addInitializerCall is not backwards
compatible
