This introduces a number of new changes: - Services are now inserted into redis with a prefix prepended to the key name. This allows for easier filtering to get only live instances. - The home page now uses an eex template for displaying all live instances for every service, determined by the last update - A "last_updated" field was added - farside.ex was added to contain all functionality related to querying for instances (WIP) - Other improvements
