Scratch pad for changes destined for the 5.8.3 release notes page.

SymbolConstants.MULTIPLE_CLASSLOADERS: when set to true (default false), enables multiple classloaders for smarter page cache invalidation.

Added methods

add(URL url, String memo) to URLChangeTracker
getChangeResourcesMemos() to URLChangeTracker
getValues() to MultiKey
New getLogicalName() method in ComponentClassResolver.
New getPlasticManager() method in PlasticProxyFactory
New getPageNames() method in BeanBlockOverrideSource

Non-backward-compatible changes (but that probably won't cause problems)

New getEmbeddedElementIds() method in ComponentPageElement (internal service)
New registerClassName() method in ResourceChangeTracker (internal service)
New clearClassName() method in ResourceChangeTracker (internal service)
