Changed request log to decode URI encoded request path (UTF-8 support)

While trying to debug a request that contains UTF-8 characters I was unable to understand what was the request path as it was URL encoded.
For example: 
>> GET /luz4u/LectureType:%D7%A1%D7%9E%D7%A0%D7%A8%D7%99%D7%95%D7%9F%20%D7%95%D7%A9%D7%99%D7%A2%D7%95%D7%A8 HTTP/1.1
This commit would make it appear as:
>> GET /luz4u/LectureType:סמנריון ושיעור

I have removed the protocol version on the way. Can be added.
