[zeromq-dev] re binary star server example in python

[Rob Fowler]

I, hopefully fixed (and have tested), the python binary star server example.
I didn't want to use the cleaner reactor example that follows, possibly 
unlike most others, as I have my own loop and want to integrate it to my 
existing code.
The logic in the command line parsing seemed to be so wrong it was maybe 
never run, but confusingly to me, the rest of the code is non trivial 
yet fundamentally correct.
I had to make a few changes. Here is a diff or the few lines I changed:

Quite possibly the HEARTBEAT stuff is not 100% what is meant to be done 
but it seems to work (and could never have worked before), I am sure 
trivial perusal by someone 'in the know' can correct me if I am wrong.
