Bad accessibility, poor code, and injects ads.

There is really far too much wrong with this plugin that I have time to write down, so I’ll stick with the hallmark badness:

1. This plugin uses <span> elements as buttons, which is a poor practice for accessibility. The author does not shim in a11y tabbing or hints for screen readers, so the visually impaired will have a poor time viewing or interacting with the swatches, if at all.

2. The plugin injects advertisements via admin notifications. This is unacceptable.
