Moves config to Tools group; shorter label
Moves config to Tools group; shorter label

SwiftLint is a tool, so I think its settings should be under Tools; this also avoids cluttering the top level of the settings dialogue.

Also, "Configuration" is redundant; we know that we are in the settings dialog! Hence, shortening that.
