Deny access to all dot files and dirs by default (except .well-known)
Update nginx rules accordingly and pass denied requests to Pico rather than letting nginx send a 404 response
With Pico 1.0 you had to setup URL rewriting (e.g. using `mod_rewrite` on Apache) in a way that rewritten URLs follow the `QUERY_STRING` principles. Starting with version 1.1, Pico additionally supports the `REQUEST_URI` routing method, what allows you to simply rewrite all requests to just `index.php`. Pico then reads the requested page from the `REQUEST_URI` environment variable provided by the webserver. Please note that `QUERY_STRING` takes precedence over `REQUEST_URI`.
