[etwist] Generates apache's mod_concat-like urls for js and css Uses the lists of js, css and ie_css included in order to generate urls compatible with Apache mod_concat (ie: http://test.fr/??file1.js,file2.js). Css files may use `media` option or may be for IE only ; this patch does not concatenate css filenames for different media types or different IE specs. It concatenates only files served under cubicweb's `data` urls and keeps original include order. The generated urls are added to the HTML header as usual. HOW-TO: - calling HTMLHead(datadir_url) will enable the url concatenation - calling HTMLHead() will not benefit of url concatenation IMPORTANT NOTE: - fckeditor can no more be served under `/data/` segment
