[PATCH] gitweb: Avoid overflowing page body frame with large images

When displaying a blob in gitweb, if it's an image, specify constraints for
maximum display width and height to prevent the image from overflowing the
frame of the enclosing page_body div.

This change assumes that it is more desirable to see the whole image without
scrolling (new behavior) than it is to see every pixel without zooming
(previous behavior).

This is an updated copy of this patch.

Could I request a thumbs up, thumbs down, or thumbs sideways from those who develop gitweb?

Thanks,
Andrew Keller
