[xwiki-devs] [xwiki-users] outputting cache-related headers from XWiki

(moving to devs since it's an internal issue): the method XWikiServletResponse.setHeader was calling addHeader.

http://jira.xwiki.org/jira/browse/XWIKI-6106 is opened.
(it concerns the trunk as well).

Since I applied this fix on my development machine, I can set a cache-header!
