Should alert compile-time errors

[hacksparrow]

Currently Forever does not inform the user of compile-time errors, and makes it look like the script is running successfully. Even though error event is logged in the log file, it might be a good idea to inform the user explicitly that the script failed to execute because of such and such errors.

Also, there is probably no need for proceeding any further if a fatal compile-time error is detected.

This is fixed in a variation of #344. You should be using --minUptime
