[Website] Wrong copyright year

Not really a bug, but I think it's important:

The MuseScore AboutBox says "(C) 1999-2009". As of 2011, this is a bit outdated. (The website footer reads 2002-2010, which is exactly one year better but still wrong).

These dates might give the impression that there's no development since (especially to non-English users/visitors, because they might see old news items on the main page and an empty forum).
