 This improves the new image sizing features and implements new thumbnails.

 Instead of a single thumbnail, images can now have multiple intermediate
 sizes.  By default there's a Thumbnail size and a Medium size.  These are
 generated at upload time and stored in the image metadata as a new array
 element 'sizes'.  There's a hook so plugins can include additional sizes.

 The new thumbnail size is 150x150, cropped to a square.  The new design
 calls for 75x75 square thumbs; I decided on 150x150 because it's closer to
 the old size or 128x96, but can be scaled in the browser to half size
 without ugly artefacts.

 get_attachment_thumb_url() and get_attachment_icon_src() will return the
 new thumbnail if it exists, and fall back to the old one if it does not.
