Dialog Polyfill Versions Save

• Fixes a crash with Shadow DOM
• Fixes a crash with finding the form submitter in Safari

• Supports formmethod to override/change <form method>, so e.g., a button could specifically force formmethod="dialog"
• Handles <form method="dialog"> inside a Shadow Root (no longer submits the form as if it was a GET)
• Fixed TypeScript definitions

• Fixes TypeScript definitions file issue. No code changes.

• Better support for Shadow DOM
• Forwards mousedown and mouseup events on backdrop

• Adds basic support for a dialog inside Shadow DOM.

As the polyfill doesn't insert its own CSS in either SD or regular cases, you'll need to add the CSS to the host.

Ships the polyfill as an ES Module.

The NPM-published release now contains both dist/dialog-polyfill.js (as before) and dist/dialog-polyfill.esm.js, which includes export default dialogPolyfill;. See #164 for more information.

This is 0.5.0 because it could break previous users of the 0.4.x branch.
