Don't wrap an image with <figure> if no <figcaption> is present

Description

I'm helping a client make their sites more accessible to people with diabilities. redactor is wrapping images a <figure> element. <figure> is only useful when it associates an image with a <figcaption>. A <figure> without a <figcaption> makes no sense. It's confusing for screenreader users (the screenreader will announce "figure", then nothing).

I'm afraid the Redactor editor itself does make some opinionated decisions about such things. The markup for image tags isn't anything that we're able to influence in a meaningful way.
