Send notification to subscribers upon adding new Shared URL

[gammaw]

Email template:

[MAG] has just shared [MAG]'s article: [Article name]

Maybe the magazines should be added to the urls component so when adding a shared url the magazine is linked to that url.

Good idea! And we could define for each magazine the corresponding user email addresses.

It's important though that filling the magazine with the shared URL is a mandatory action.

Updated spec:

• When a new SharedURL entry is added, send email notification to all subscribers (of the article);
• Subject of email: "EM GUIDE: New share on [ARTICLE TITLE]
• Email body:
  • Print the newly added SharedURL entry;
  • Embed "Open article" button;
