New block needed for image captions

[vossisboss]

Our new design (and also our old design) didn't have very many good options for adding captions to images. We need either a new type of image block or a new type of text block to provide captions to images that need them. Whichever option we pursue will need to be accessible and provide a good experience for screenreader users.
