EXIF tag plugin

I've wrote EXIF tag plugin for Jekyll .

If you write text like this:

{% raw %}{% img /images/2012/03/first_shot_orion.jpg %}{% endraw %}

{% raw %}{% exif /images/2012/03/first_shot_orion.jpg %}{% endraw %}

You will see the converted result like this:

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

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