Image with EXIF tag plugin

I've modified Image tag plugin into Image with EXIF tag plugin based on the idea of mattn-san's comment. (Thanks, mattn-san!)

If you write text like this:

{% img_with_exif /images/2012/03/first_shot_orion.jpg %}

You will see the converted result like this:

Focal Length 10.0 mm F5.6 NIKON D5000 ISO 1600 Exposure Time 15 second 2010-11-05 01:32:07 +0900

The title and alt attribute have EXIF data of thie image file.
