Extra:VisualEditorTest

This was my first visual edit on a wiki using a self installed VisualEditor. Finally got this one working for this wiki. The documentation is apparently not self-explanatory. On Wikimedia projects I have probably done about ten visual edits so far. That's not really much.

## VisualEditor
wfLoadExtension( 'VisualEditor' );
$wgVisualEditorAvailableNamespaces = [
	NS_EXTRA => true
	];
$wgVirtualRestConfig['modules']['parsoid'] = [
	'url' => 'https://sandbox.semantic-mediawiki.org:8143',
	'domain' => 'sandbox.semantic-mediawiki.org'
	];

Parsoid via stunnel is at https://sandbox.semantic-mediawiki.org:8143/.

RESTbase via stunnel is at https://sandbox.semantic-mediawiki.org:7232/sandbox.semantic-mediawiki.org/v1/. When enabled via VisualEditor neither Parsoid nor RESTbase work. I am very pissed indeed. I am not sure if it is good or bad that both servers are running flawlessly in and environment isolated from each other.

curl https://sandbox.semantic-mediawiki.org:7232/sandbox.semantic-mediawiki.org/v1/page/html/Main_Page

... works, so why the heck ....
