Replaced *args with args.

[jyapayne]

*args caused dictionary packets to get stripped of values and
as a result, keys were only left, which is useless.

Given this code example:

from socketIO_client import SocketIO, LoggingNamespace

def message(*message):
    print 'message:', message

with SocketIO('209.197.176.152', 5555, LoggingNamespace) as socketIO:
    socketIO.on('event', message)
    socketIO.wait()

The old code would have taken a packet with this dictionary:

{'something': 'important_data'}

and the output of the callback would have been

message: ('something',)

With the PR, it is correctly this output:

message: ({'something': 'important_data'},)

Whoops, I deleted the branch for this pull request by mistake. Going to try to merge manually...
