Add dojo resources listing #18
Description
Currently Torii doesn't explicitly list the resources in the world (events, models, contracts etc..).
This issue would track such implementation, where a table for the world resources would be added to Torii in order to query the resources by namespace for instance.
We could add at the same time the permissions indexing, which could be coupled with the resource itself and ease the retrieval of such data.
