[FacebookBridge] Replace 'novideo' with 'media_type'

This replaces the 'novideo' parameter with 'media_type' in order
to filter for specific content types. Currently supported:

- 'all': Returns all posts (default)
- 'video': Returns only posts including videos
- 'novideo': Returns only posts that don't include videos
