Custom validity fixes

There were some recurring issues with the custom validity implementation. Significantly, some recursion issues caused serious performance hits. Focus management was also affected.

These have now been fixed. You can find details in PR #15.

Additionally, some work has been added to allow you to override the output of CSS and JS with an .env file.

Accessibility fixes

Thanks to the great work by @nchan0154, we have had some accessibility fixes on the checkbox/radio component which adds proper focus state.

PR: #8

Basic validation interface added

A developer can now:

• Have the is-error class toggle automatically based on validity of input elements
• Add a custom error message by adding a data-validation-message attribute to an element

The validation interface will also check sibling inputs when an input fails validation. This will remove the is-error class if they are valid when they were previously invalid.

Lastly, a basic Webpack setup has been added along with these changes.
