EV Checker: resulting message confusing

[WilsonKathleen]

The results of EV Checker confuse many people who don't realize that the check actually failed.

Success looks like: "ev-checker exited successfully: Success!"
Failure looks like: "ev-checker exited successfully: exit status ..."

Some people see the "ev-checker exited successfully" and ignore the following "exit status..."

Would you please change the text "ev-checker exited successfully:" to "EV Checker PASSED:" when it succeeds, and "EV Checker FAILED:" when it gets an exit status?
