Fails if php-xml not installed

[woganmay]

If the plugin is installed on a server that does not have the php-xml installed, it will just fail with an exception, that it cannot find the DOMDocument class.

Class 'DOMDocument' not found
.../plugins/rainlab/sitemap/models/Definition.php line 156

I resolved it by installing php7.0-xml on my instance:

sudo apt-get install php7.0-xml

Would be nice if the plugin could check for that module's existence before installing.

Or at the very least this should be included in the readme / documentation

Thank you @woganmay this fixed the error for me!
