This pull request adds support for og:image:alt (partially solves #10).

This is how the alt tag is generated:

ogp_image_alt is a new option for conf.py. Any string provided with this option will be used as alt text
If no string is provided, opengraph.py will try to automatically use site_name as alt text. If site_name is not available, htp.text will be used instead.
The user also has the option to completely turn off alt text, by setting ogp_image_alt to False.
This pull request also includes an additional test and an update to README.md.

According to opg.me any page that includes an og:image should also inclode an og:image:alt. This would not only increase compliance with opg but might also increase search engine visibility.
