Old version dates for wp-logo.png images uses cached images on 3.2 upgrade

[zekeweeks]

I upgraded a 3.1 install to 3.2 and noticed that wp-logo.png displays 3.1's old 32px version in the new Admin header. Refreshing browser cache fixes it for users, but it looks like colors-fresh.css and colors-classic.css append ?ver=20100531 and ?ver=20101102 respectively to the file URL (probably to avoid this problem?)

Looks like the 16px files were last updated on 2011-05-04, so I've attached a patch making use of that date. (This is my first patch submitted to WordPress, so please let me know if this should be done differently. :-) )

Thanks for the patch - one note, don't patch the compressed files. We handle those on commit. Keeps patches fresher (this one didn't apply due to unrelated changes in the file since then) and allows us to verify that things match.

Congrats on patch # 1!
