Patch by Takashi Toyoshima <toyoshim@chromium.org> on 2011-08-31
Reviewed by Kent Tamura.

Some layout tests for WebSocket raised Exception to prevent unnecessary
pywebsocket warning. But it doesn't work any more on pywebsocket 0.6b4.
Now pywebsocket support AbortedByUserException to prevent warning.
This change make raise AbortedByUserException instead of Exception.

handshake-fail-by-prepended-null_wsh.py didn't use Exception, but
expected abnormal closure on sending response could raise unexpected
Exception by chance. This change also takes care of it.
