This changes how ripgrep emit exit status codes. In particular, any error that occurs while searching will now cause ripgrep to emit a `2` exit code, where as it previously would emit either a `0` or a `1` code based on whether it matched or not. That is, ripgrep would only emit a `2` exit code for a catastrophic error. This tweak includes additional logic that GNU grep adheres to, which seems like good sense. Namely, if -q/--quiet is given, and an error occurs and a match occurs, then ripgrep will emit a `0` exit code. Closes #1159
