Alpha: rework reward storage.

Browse Source 
We now keep track per delegate and per cycle of three distinct "frozen
balance": one for the bond, one for the fees, one for the rewards.
All tokens frozen during cycle 'N' are unfrozen at the end of the
cycle 'N+5'.

The frozen bond and fees count allows to gain rolls. The frozen
rewards do not.
