Update time-based constants

Browse source 
This updated various time-based constants to more closely reflect values
appropriate to Dogecoin:

* Minimum number of blocks and blockchain size are increased for
pruning. In comparison to Bitcoin this uses 24 hours as a minimum,
rather than 48, although given blocks are rarely full this likely
reflects a lot longer in reality.
