Add web-socket-js support with packet re-ordering.

Browse Source 
- web-socket-js is from http://github.com/gimite/web-socket-js. It is
  a flash object that emultates WebSockets.

Unfortunately, events (or packets) from the web-socket-js object can
get re-ordered so we need to know the packet order.

- So wsproxy.py prepends the sequence number of the packet when
  sending.

- If the client receives packets out of order it queues them up and
  scans the queue for the sequence number it's looking for until
  things are back on track. Gross, but hey: It works!

- Also, add packet sequence checking to wstest.*
