Title: XWIKI-106: Cache issues with IE and proxy caches 

JIRA: http://jira.xwiki.org/browse/XWIKI-106

This commit replace the standard "download" action to the "downloadrev" action when you generate an attachment URL to avoid cache issue. If the file has changed, then the revision is not the same, and it will be reflected into the URL.
