#187 Missing 'global $debug_object;'

[Slava]

Directive 'global $debug_object;' is missing inside several functions. Please, let's see attached diff-file.

[LogMANOriginal]

The global debug object was never fully supported and is obsolete. Version 2.0RC1 and later introduces a Debug class that you can attach your own debug handler to:

require_once 'Debug.php'

use simplehtmldom\Debug;

Debug::setDebugHandler(function($message){ echo $message; });
Debug::enable();
