Title: lacking apache config to handle url that contains %2f (/) or %5c (\)

in the eztagcloud, whenever the keyword contains a slash (/), we get an aggressive 404 error, eZPublish is even not executed

For example: http://ez.no/content/keyword/ez in order to search the keyword 'ez', all is ok

and when hitting http://ez.no/content/keyword/ez%2f, a 404 error is thrown
It comes from an option of apache that rejects by default url containing %2f for security reasons:
http://httpd.apache.org/docs/2.2/mod/core.html#allowencodedslashes

This reason is good, but there's no security problem with eZPublish, thanks to index.php controller, there's no direct access to a file in ezpublish tree
