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.
