Adds Polar Polls support to oEmbed WhiteList

[wpeterson]

I'm submitting code to allow support for oEmbed of Polar Polls within WordPress. Polar Polls allows you to beautiful, photo based polls and share them with your friends. We've added oEmbed support for our polls to allow bloggers to include polls in their articles safely and easily.

Code changes are encapsulated in this Github Pull Request:

​https://github.com/WordPress/WordPress/pull/51

Examples of Polar embedded polls in existing articles/blogs:

I'm going to recommend wontfix for this. Although it seems harsh, please read the reason given on #25265, specifically 1:ticket:25265. Maturity of the service is an important factor, despite good technical implementation, documentation, etc.

I also recommend close. In addition to the comment on #25265, more information on how WordPress decides which oEmbed providers to include (whitelist) can be found on ​Design Decisions page in the Core Contributor Handbook.

I would suggest creating a plugin for the service, and uploading it to the wordpress.org plugin repo to determine how much interest there is for the service from other WordPress users.
