Better folder structure.
Added the WSConnection class and its _greeting method that handles the handshake.
Added logging and wslib.setVerbose & wslib.setQuiet to handle streamed debugging and logging.
Added WSConnection._read_header that analyses the header of every WebSocket frame.
Added a NOTES file to help my forgetful mind
Added wslib.WSPayload that handles the decryption of every frames payload.
The wslib.WSConnection class is an asyncore dispatcher. Instantiation is possible from now on and the received data gets encapsulated into the new WSPayload objects.
Added imports and changed some calls to the python3 compatible kind.
