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).
