[ActiveSupport] Patches needing review: re-organization of #to_query methods, preservation of XML/JSON content-type

Just a quick pointer to some ActiveSupport patches hoping for reviews:

Puts Array#to_query and Object#to_query in the right places in
ActiveSupport - http://dev.rubyonrails.org/ticket/10395

Preserve user-specified content type for XML and JSON rendering
(currently it's overridden and set to Mime::XML/Mimi::JSON -
http://dev.rubyonrails.org/ticket/10388

Oh and a tiny patch for inconsistency in #to_sentence:
http://dev.rubyonrails.org/ticket/10390 and a trivial doc patch for
Date.yesterday and Date.today: http://dev.rubyonrails.org/ticket/10375

Reviews appreciated! Thanks!

Cheers,
Chu Yeow

PS Rails 2.0 is almost here it seems: http://dev.rubyonrails.org/changeset/8321

On the subject of really teenie-tinies, there's http://dev.rubyonrails.org/ticket/10380
The default double render error message still goes on about filters
needing to explicitly return false, which is no longer accurate

Just a bump hoping to get some +1 love - I think my post got lost
since I posted it while the Core team was pushing out 2.0.0.
