ALFCOM-2816: Changes for JBoss v5.0.1.GA compatibility

- All code that resolves classpath resources goes through JBossEnabledResourceLoader with VFS support
- JBossEnabledResourcePatternResolver can handle recursion within VFS directory structures
- Reflection used to avoid runtime dependency on JBoss classes
- resource-ref declared in jboss-web.xml 
- Work around incorrect treatment of env-entry-value tag in web.xml
