Use Swagger instead of Apidocs

[tombh]

See hotosm/OpenAerialMap#86

Swagger has 3 advantages; firstly it has wider suppport, secondly it builds itself from code not comments and thirdly it enforces parameter checking in endpoints. There is already a drop-in plugin: https://github.com/glennjones/hapi-swagger It will simply require that the validate: { params: {} } properties on each endpoint are correctly populated.
