An error happened while running websocket example with latest version of cowboy

[gage]

I just cloned the code and "make rel" and ran ejabberd in live mode. An error happend when I trying to login the server in the websocket example "simpleclient.html".

[error] emulator Error in process <0.648.0> on node 'ejabberd@localhost' with exit value: {{badmatch,false},[{cowboy_router,execute,2,[{file,"src/cowboy_router.erl"},{line,37}]},{cowboy_protocol,execute,4,[{file,"src/cowboy_protocol.erl"},{line,494}]}]}

[error] <0.432.0> Supervisor ranch_conns_sup had child ranch_conns_sup started with {ranch_conns_sup,start_protocol,undefined} at <0.648.0> exit with reason no match of right hand value false in cowboy_router:execute/2 line 37 in context child_terminated

After tracing the code, I think the problem is cowboy has changed the ProtocolOpts settings spec, so I do the following fix, it seems ok now.

--- a/apps/ejabberd/src/mod_websockets.erl

Solved along with #64.
