Handle automation server crashes. When Chrome crashes, we now handle the case and support document refresh or reload.

When chrome crashes, we draw a poor man's sad tab (":-("), so that can clearly be improved.
Another thing is that if the chrome instance that crashed held several navigational entries, then that history is lost.

TEST=There are a couple of tests included, so run those (*TabCrash*) and also verify that when the chrome automation server is killed that we do the right thing.  Also check info in bug report.
BUG=25839
