[Pianod] web client how to?

[Peter Li]

Hmm, I'm in the embarrassing position of running this WebSockets thing 
and not really understanding how to use it...  Where do I find the web 
client code that presumably is supposed to connect to this?

I had to make some patches to get wsgw to build on Linux (FC17, 
ArchLinARM).  In brief:
     1) Added make rule so that IP6_CFLAGS is used
     2) Added some includes that seem to be needed
     3) Added libbsd to includes and linking; it didn't seem like there 
was an easy way to get everything working without this...
