"Colon Violation" bad phrasing

[ghost]

Describe the bug

The colon spacing rule is named "Colon", which means it shows up in logs and in Xcode as "Colon Violation", which sounds more like a threat than a warning. Pun really-really not intended.

I propose changing the rule name to "Colon Spacing", which improves the phrasing in my opinion.
