Added PoP Initialization and a Challenge Query (#207)

* added InitPoP message
* added getChallenge query to inspect challenges
* adjusted towards a unique block height identification unit: int64, not uint64
* added challenge param finished to identify challenges that weren't completed but will be part of re-issuance.
