ECOMPHP-409

* All internal classes replaced with new PSR-compliants.
* Replaced internal logics that other libraries can do better.
* Fixed strict checkings for in_array's.
* intval's are now typecasted.
* SSL stuff should still not be handled in core functions of ECom.
* Session handling should neither be handled by core-ECom (since integrations usually breaks by this). All calls to those sections are now deprecated.
* Checking for SoapClient are now done externally. getDisabledClasses is no longer required in package.
* HTTPS-checking is simplified by phpstorm.
* Some queries which normally requires an argument but is default to "null", has been fixed.
    Example:
    -    public function getRegisteredEventCallback($callbackType = RESURS_CALLBACK_TYPES::NOT_SET)
    +    public function getRegisteredEventCallback($callbackType)
* Removed curldriver version check.
* Urlencoding/Decoding dont belong to core functions. Replaced.
