Feat: Autopopulate Title from URL via Citoid API

[sambacha]

pandoc-url2cite is based on the work of the [Zotero] developers. Zotero has a set of "Translators" that are able to extract citation info from a number of specific and general web pages. These translators are written in Javascript and run within the context of the given web site. They are made to be used from the Zotero Connector browser extension, but thankfully there is a standalone Translation Server as well. To avoid the effort required to automatically start and manage this server locally, pandoc-url2cite instead uses a publicly accessible instance of this server provided by Wikipedia with a public REST API.
