Wordpress-ios: Caption shortcode support.

[diegoreymendez]

Description

We need Aztec to support the caption shortcode. Extensive details can be found in the original issue here.

Details

This issue depends on another one from Aztec: https://github.com/wordpress-mobile/AztecEditor-iOS/issues/723.

In terms of WPiOS the work that needs to be done is to convert caption shortcodes to figure + figcaption tags.

Here's an example showing standard figcaption usage.

<figure>
  <img src="img_pulpit.jpg" alt="The Pulpit Rock" width="304" height="228">
  <figcaption>Fig1. - A view of the pulpit rock in Norway.</figcaption>
</figure>

Support request for option to add caption to images. (On iOS 11, so possibly not able to use the older editor without other issues popping up.)

I've also got a user asking about adding captions to images in Aztec.

Have personally seen 5+ requests for ability to add captions in this editor this week.

Most recent, internal ref: #239621-h

Thanks @jklausa and @sarahblackstock.

Considering the amount of interest, we'll try to focus on this for the next release.

Even though 9.2 has entered code freeze, we'll try to add this feature before the release.

We told the user it will be soon fixed in next release which is why user enquired again about it

@krutidugade - The feature is delayed due to complications. We'll report it here as soon as there are news.

This feature has been merged into the library in https://github.com/wordpress-mobile/AztecEditor-iOS/pull/910 and will be integrated into WPiOS shortly.
