Build framework for jsr-276 metadata

Currently, the maven-faces-plugin will not recognize the proposed jsr-276 metadata - transform12.xsl has very specific rules for what gets transformed to the faces-config.xml file. We need to change this so that jsr-276 metadata that is added will show up in faces-config.xml

Additionally, we want the rules for the new metadata to be 'generic' such that when new metadata elements are added we don't have to go back and change the xsl file.

Finally, any changes should be backward compatible such that things will work either with, or without, the new metadata.
