First cut of Facebook integration:

1) Web Script framework extensions for supporting the development of Alfresco based Facebook applications
2) Sample Document Library Facebook application
3) FormData enhancements for supporting request args retrieval for multipart/form-data encoding
4) Sort order added to Search Javascript API

Note: Stuff needs commenting, tidy up, but at least it's in SVN.
