Twenty Ten: attachment images should be centered

[lancewillett]

Originally reported by photomatt.

Images in single attachment template should be centered. Images that are narrower than the full-width maximum of 900 pixels are currently left-aligned.

The most common case is when using a gallery, where the gallery settings are set to link to attachment pages for the images, but this applies to any image viewed with the attachment template.

Aside: If we're going to use trunk and the master for Twenty Ten development, we need to copy the 1.0.3 changes from the themes dir into trunk. I believe trunk is currently behind.

This was actually 1.0.4 of Twenty Ten I think. Ian sent it to me via zip a week or two ago; he is waiting on some changes to the theme repo thanks to slug sanitization (Twenty Ten = twenty-ten, not twentyten).

We're sync'd. Closing as fixed.
