[ES40-developers] Patch: graceful shutdown if syntax error in config

[brian w. <bdw...@in...>]

It looks like the configurator doesn't catch missing '}' in the
configuration file.  This patch catches when theSystem doesn't get setup
correctly and exits gracefully instead of segfaulting when trying to
load the rom file.
