Accessdate doesn't use preferred format

Per comments on the ProveIt talk page:

"When using cite web and a few others the tool automatically fills in the 
accessdate using the form "2011-01-08" when the full written form is preferred 
i.e., "January 8, 2011" or "8 January 2011". See, e.g., the example accessdates 
in the documentation for {{cite web}} and {{cite news}}, the examples at 
WP:CITET, or the retrieval dates in today's featured article. There is a 
possible WP:ENGVAR issue if you default the style to January 8, 2011 over 8 
January 2011; someone down the line might say "hey, why are you choosing for us 
the middle endian form over the little endian form" and so on, but anyone can 
change this and there are manifestly more articles written by people who would 
naturally choose month day year over other formats. Ideally, though, the tool 
would recognize the date format at the start of the article and choose the 
accesdate format from that example and, if not present, would default to the 
most common format.--Fuhghettaboutit (talk) 17:43, 8 January 2011 (UTC)"
