* ASSignpost: Add support for the os_signpost API - Removes support for colored intervals. These weren't really useful and they aren't part of the signpost api. - Fixes an issue with range controller interval logging. - Adds an interval for interface orientation changes. * Rename * Support Xcode 9 * Commentary
