Merged from BRANCHES/DEV/KEVINR:

. NodeInfo panel and Ajax client library
 - Rewrite of Node Info panel
 - Alfresco common DOM methods refactored into namespaced object (YUI/Dojo style) Alfresco.Dom
 - Addition of useful DOM and 'smart' alignment method to common.js
 - OpenSearch now uses additional namespace for it's global method handlers: Alfresco.OpenSearchEngine
 - Temporary icons added for pop-up node info panel
. Additional FreeMarker model API method "cropContent(contentprop, length)" to return the first N bytes of a content stream - auto converted to plain/text from all supported transformation mimetypes
. DownloadContentServlet now handles ContentIOException more gracefully
. AbstractContentReader fixed to handle empty file data when requesting N characters from a content stream

. Yahoo scripts move to PageTag rendering as appropriate
. Refactoring of existing ajax components that output Yahoo scripts
