[VOTE] Modify Header copyright

Hi, The current header copyright says: "Copyright 2006-2007, XpertNet SARL, and individual contributors as indicated by the contributors.txt." 2 issues: - The sentence is not english - We don't have such a file I propose that we change it in favor of: "Copyright 2006-2007, XpertNet SARL, and individual contributors." Main Reason: - We don't specify where the contributors are listed which means we can decide to change that location. For example a list of contributors is on http://www.xwiki.org/xwiki/bin/view/Community/ HallOfFame#HContributors but it's far from being accurate. Tomorrow we may use another strategy or another location and we'd rather not change all headers. So better not specify where we define them. Another location is SVN. Here's my +1 to that. I also propose that we continue listing contributors on that HallOfFame page. Unfortunately I've been the only one adding names there. I need help. Thanks -Vincent
