Version 2.4.0

Reworked parts of javascript decryption, templates and the python plugin.

Works better with relative paths, but setting correct site_url is still necessary for experimental search index decryption to work.

Will try to decrypt with a saved password (remember_password) from one url level up and from site_url. This is treated as fallback and won't trigger decryption_failure_message.

Changed the manner encryptcontent alters the search index to be less likely to fail. Please always double-check content of /site/search/search_index.json!

Describe a way of patching mkdocs-material to enable experimental search index decryption.

Provide a functionality to self-host crypto-js.

Introduce new method to inject decrypt-form.tpl to theme. Use if the standard way of replacing page.content won't work, f.ex. at the blog plugin of mkdocs-material-insiders.

Enable reload-js to re-execute a script by id and removed jquery dependency.
