Accesslint.js Versions Save

• Removes POST request to access_lint/errors for server logging
• Fixes capybara/poltergeist errors
• console messages are more succinct and useful

• Console warnings are unique across a single page load.

• Log each violation individually, making it easier to scan the descriptions in the console.

Introduce DOM mutation handling.

This release disables color contrast checking.

Right now axe-core scrolls the page when checking color contrast, which is ok in tests, but not ideal for smoke testing and development.

There is a configuration option that will fix this, pending release: https://github.com/dequelabs/axe-core/pull/148
