Removed the AliasReplacingBeanDefinitionParser class from the Region/bean definition parsing hierarchy moving the remaining methods: getBeanClass, getRegionFactoryClass and isSubRegion to the AbstractRegionParser class.  Modified ClientRegionParser to extends AbstractRegionParser directly and provide an supported doParseRegion method since ClientRegionParser overrides doParse directly.  Modified AbstractRegionParser class to extend org.springframework.beans.factory.xml.AbstractSingleBeanDefinitionParser directly changing the overridden doParseInternal method from AliasReplacingBeanDefinitionParser to the overridden to doParse method from AbstractSingleBeanDefintionParser.
