Title: Include the instance name in the rule id (fixes #177)

This fixes #177. The addRules method of definition.js checks rule inheritance using the id of the rule, and only adds rules from ancestors if the id is different. However, without this patch, foo/line-color and bar/line-color have the same id and therefore aren't recognised as applying to different instances.
