bug 2502 fixed: better handling of non-latin tags and multilanguage tags on

tags.php with mode letter.

We can't rely on url_name because it always start with "_" when the tag looks
like "[lang...". Instead we compute a str2url on the name, but once it has been
rendered by Extended Description. To avoid useless computations, I have added a
cache on the tag_alpha_compare function. Tested on a 175 tags set, speed is
good.
