Link metadata retrieval

[erlend-sh]

When a link is added, meta-data could be automatically pulled for it with something like link-preview or embed-service (they do slightly different things, but the exact difference is unclear to me).

Retrieve website metadata such as

• title
• description
• preview image
• author
• and more

from OpenGraph, Google, Schema.org and Twitter compliant sites

Description and preview image should probably be reserved for an optional “rich view” of some sort, but title and author would be great to include by default.

I just went through the link-preview, but after digging into the source code, I found out that unfortunately author wasn't actually provided by it. Instead, it only provides title, description, domain, and image_url.

Should we include title by default with optional "rich view" (image and description) that is defaulted to be turned off but could be turned on for every list?

Sounds good to me. What do you think @raffomania ?

Opened a PR for title enabled by default (#63), please let me know if there any further improvement needed
