ApiController#capabilities

External apps that use the api are able to query the api to find out some
parameters of the API. It currently returns:
* minimum and maximum API versions that can be used.
* maximum area that can be requested in a bbox request in square degrees
* number of tracepoints that are returned in each tracepoints page
