Closes #53.
Adds full support for image, video, and audio og tags:
[x] Relative path support for images
[ ] Relative path support for video and audio
[ ] Automatic mime type detection and validation
[ ] Width/Height tag support for images
[ ] Width/Height tag support for video
Currently, whether an image is configured in conf.py or in field lists, if it starts with / it is treated as relative to the root, if it doesn't it's treated relative to the current document. I think this functionality is fine and allows you to set up different images for each file without field lists if you use the same naming scheme (i.e. `images/docname/opengraph.png). but open to comments.
