Title: handle ConResCtxt to allow moreConnection query

This is another approach to #56.
Maybe both approaches have their right to exist.
The query API uri has to be changed if we want to query for more connections as @dol has discoverd.

The reference gets returned in the /connections result and can then be used in a request like:
`/v1/moreConnections?reference=ca.012807207.1336656571%231&forwardCount=3`
or
`/v1/moreConnections?reference=ca.012807207.1336656571%231&backwardCount=6`
where only one of forwardCount and backwardCount shall be set and a max of 6 is allowed.
This returnes an array of connections and a new `reference` to be used for subsequent moreConnection requests.
The `fields` parameter can be set to the same as with the `/v1/connections` query to limit the result.

With this approach the query for more connections is only done on request by the API consumer.

i'll do the documentation if you consider merging.
