Combine `module_name` and `selector`, but don't prepend a `.` or `#`
 because this value will be inserted into the HTML page as `class=` or `id=`
 @param module_name [String] A CSS module name
 @param selector [String] A would-be DOM selector (without the leading `.` or `#`)
 @return [String] An opaque selector for this module-selector pair
