Enable automatic escaping of all stuff rendered through ".html.jinja" templates

Took me a while to figure out why quart suddenly stopped escaping the variables i rendered.
As it turns out if you rename your templates to "whatever.html.jinja" (was a suggestion to make vscode shut up about the jinja code in them) quart/jinja (idk where it happens) stops escaping the strings you pass into the templates. The rest continues to work as expected. You can even re-enable escaping in the templates on a per-value basis (with the "|e" pipe thingy). For now I have renamed back to "just.html", but I am wondering whether there is a way to get it to escape both types...

You can override Quart.select_jinja_autoescape(filename) to return True when a given filename should have autoescape enabled. The default looks for the extensions html, htm, xml, xhtml, and svg.

I'm also pretty sure there's a few extensions for VS Code that add Jinja template support.
