Update time-based constants

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

* Number of blocks to look back for BIP 66 enforcement is doubled on
main net (to about a day and a half's worth, vs 5 days on Bitcoin),
and raised to 1,000 on testnet (bringing it up to the same quantity
as Bitcoin testnet).
* BIP 66 enforcement cut-offs are scaled up appropriate.
* 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.
