[+] Added possibility to find your mistake with ease just use .debug()

How To Use:
To use the debugging option just call the .debug() method.

2. Give you the exact error message if there is an "URL_ERROR"

Normal request:
if(!new AdvancedLicense("YourLicense", "http://your.domain.com/License/verify.php", this).register()) return;

Request in debugging mode:
if(!new AdvancedLicense("YourLicense", "http://your.domain.com/License/verify.php", this).debug().register()) return;
