wstest*. Fix Opera problems. Flash policy. Misc bugs.

Lame. Opera doesn't support javascript reduce().

Also, Opera seems to just plain be pathetic when it comes to
delivering the web-socket-js events. Around 1/5 to 1/3 of all received
packets are never received as an event at all.

- Change default delay for send side to 10ms.

- Use a textarea for errors so that even without console.* support
  (ala firebug) we still see the errors that are happening.
