More strict "ack"-message handling
Maybe this is not a real bug, but I think gitmate should enforce a stricter format for ack-unack-comments.
Steps to reproduce
What is the current bug behavior?
gitmate reacts on a normal sentence that contains "ack", but it's not meant to ack something actually.
What is the expected correct behavior?
gitmate ignoring the comment.
