- Including private fields/methods when generating hash

Track updated classes on dev mode refresh to incrementally compute pseudo-dependent-scope in Bootstrapper generator.
Use fully qualified class for dependent scope cache and fix handling of deferred types in MetaClassCache.
Performance improvement when scanning for i18n bundles

- Only scan once to find all .json resources for all bundles
Use Predicate to filter file paths when scanning in GwtValidationGenerator.
Only scan urls with ErraiApp.properties or json files from Bundle annotations in TranslationServiceGenerator.
Fixed rendering of zero-length array literal
