Handle errors raised by plugins more gracefully in mod_wsgi.

This started as an effort to display a more useful error message in the
Apache error log if retrieving the schema failed. I broadened the scope
a little to include limiting the output in the Apache error log
so errors are easier to find.

This adds a new configuration option, startup_traceback. Outside of
lite-server.py it is False by default so does not display the traceback
that lead to the StandardError being raised. This makes the mod_wsgi
error much easier to follow.
