better error handling/logging for failed builds

[joeycozza]

• Wrap the index-revision-replace code in a try/catch. Log the error message in the catch, but DON'T throw the error.
  • By not throwing the error in the plugin, the already existing error logging will log the underlying issues as expected
• add, (and commented out) a tap into afterCompile hook to check if errors exist. This may help in debugging issues in the future since the whole stack trace is logged.

The logging will look like this. (ignore the joey brosky logs of course. :) )
