Adds support for displaying inline images within content blocks.

Makes use of `WPImageGetter` to load the images in ImageSpans.
Added image spans directly instead of using Html.fromHtml().

This allows for other block actions like linking to still work. I had to limit the image size to 240dp, otherwise the images would load blank white.
Moved `imageGetter` creation outside of the media loop.
