OpenMatch Transaction

[patrickwieth]

We want to open matches first and then report later, because we want the match id and votingRights early (so that the user does not have to wait for this)

OpenMatch tx

• creates and returns a matchId
• assigns votingRights to the players

players who have an openMatch already cannot get votingRights or rewards on extra opened matches
after 12.000 blocks open matches expire and are deleted

ReportMatch tx changes in so far that it not longer generates an Id and does not assign new votingRights
