- Introduces a url service that can be initialised
- Added a concept of Resources and resource config.json that contains details about the resources in the system that we may want to make customisable
- Note that individual resources know how to create their own Urls... this is important for later
- Url Service loads all of the resources, and stores their URLs
- The UrlService binds to all events, so that when a resource changes its url and related data can be updated if needed
- There is a temporary config guard so that this can be turned off easily
