Renamed meta/excerpt meta/generate-excerpt

- This function is quite different to the others, as it generates an excerpt from HTML (truncating)
- Most functions in the meta data folder just contain content negotiation logic, like if post then feature_image else cover_image type things
- This function is more like a library and shouldn't live in Ghost, it should probably be in @tryghost/helpers
- It's definitely something we'd love to rewrite to work better tooooo
