Allow to open editor URL via WSL

[flyingangel]

At the moment we can open the editor directly using a protocol. Ex: vscode://file/%file:%line

If we use PrettyPageHandler::setEditor(EDITOR_VSCODE)

This only allow us to open a file in local machine.

But if we want to open a file inside a WSL container (while VSCode is on Windows system), we would need to improve the protocol to become:

vscode://vscode-remote/wsl+Ubuntu/%file:%line

The general supported format is:

vscode://vscode-remote/<remote-type+identifier>/<path>:<line>

So we would need to add an additional config for the remote setting. Ex:

PrettyPageHandler::setEditor(EDITOR_VSCODE_REMOTE)
PrettyPageHandler::setEditorRemoteType('wsl+Ubuntu')

Ubuntu can be fetched from env variable $WSL_DISTRO_NAME if we want to guess automatically if the type is wsl.

Open Files In An Editor

	Adding your own editor is simple:
	```php
	$handler->setEditor(function($file, $line) {
	return "whatever://open?file=$file&line=$line";
	});
	```
	You can add [IntelliJ Platform](https://github.com/pinepain/PhpStormOpener#phpstormopener) support like this:
	```php
	$handler->setEditor(
	function ($file, $line) {
	// if your development server is not local it's good to map remote files to local
	$translations = array('^' . __DIR__ => '~/Development/PhpStormOpener'); // change to your path
	foreach ($translations as $from => $to) {
	$file = preg_replace('#' . $from . '#', $to, $file, 1);
	}
	// IntelliJ platform requires that you send an Ajax request, else the browser will quit the page
	return array(
	'url' => "http://localhost:63342/api/file/?file=$file&line=$line",
	'ajax' => true
	);
	}
	);
	```
