Bugfix:URLLoader can't send parameters data when using get method.

[lovoror]

Fixed using code followed:
awayjs/core/lib/net/URLLoader.ts line 171

private getRequest(request:URLRequest):void
{
   try {
			if(request.data !=null){
				this._XHR.open(request.method, request.url + "?" + request.data, request.async);
			}else{
				this._XHR.open(request.method, request.url, request.async);
			}
			this.setResponseType(this._XHR, this._dataFormat);
			this._XHR.send(); // No data to send
		} catch (e /* <XMLHttpRequestException> */) {
			this.handleXmlHttpRequestException(e);
		}
}
