Add examples of binary sending with blobs about ofxlibwebsockets

[arthursw]

I've try to make the binary examples work on OS X Maverick (10.9.1) and linux, neither worked.
I always get errors like:

new connection open
1440000
realloc from 1024 to 1440000
ERROR writing to socket

When I debug, I end up in the sendBinary function of Connection.cpp (line 90):

                n = libwebsocket_write(ws, &binaryBuf[LWS_SEND_BUFFER_PRE_PADDING], size, LWS_WRITE_BINARY);

and n is always negative (I think it should not be).

I've tried the examples of labatrockwell/ofxLibwebsockets as well as blob examples of zebradog / ofxLibwebsockets, neither worked.

Any ideas?
