Function CleanPaths

tools/filetools.go:93–116

CleanPaths splits the given `paths` argument by the delimiter argument, and then "cleans" that path according to the path.Clean function (see https://golang.org/pkg/path#Clean). Note always cleans to '/' path separators regardless of platform (git friendly)
