Add colour option for -p's slow test output
Created by: JoshCheek
Worked on with @cdemyanovich during waza at @8thlight
When running RSpec with the --profile option, slow tests are displayed in red. This causes me to think my tests fail!
This patch introduces the --slow-color
(akas: --slow-colour
, -s
) option to allow the color to be changed. It defaults to cyan.
