Option to embed JS and CSS inline

[janwalther]

In my setup the webserver allows public access only to the folder where the front controller is located in (/var/www/html/public). When trying to use the debugbar it tries to embed JS and CSS files:

<link rel="stylesheet" type="text/css" href="/vendor/maximebf/debugbar/src/DebugBar/Resources/openhandler.css">
<script type="text/javascript" src="/vendor/maximebf/debugbar/src/DebugBar/Resources/vendor/jquery/dist/jquery.min.js"></script>

The problem is that the vendor folder is not publicly accessible (for security reasons) and thus those CSS and JS files cannot be loaded. That is why I would appreciate a setting to embed JS and CSS code inline.
This is possible by using $renderer->dumpJSAssets() and $renderer->dumpCSSAssets().

I created a PR so we can discuss the issue there.
