Added Python simulator of new difficulty adjustment algorithm.
Add the new difficulty adjustment algorithm, which replaces the simple average over 2016 blocks with a faster-acting 144-tap Parks and McClellan FIR filter, and adjustments every 9 blocks with a gain of 0.1025 and limiter of 1.055.
Prepare for deployment of difficulty adjustment filter to production network by adding a threshold block after which the new difficulty adjustment algorithm takes over, for both mainnet and testnet.
Schedule fix of forking bug introduced in git-master to coincide with difficulty adjustment filter hard-fork.
Fixed two related bugs in the freicoin "accounts" system. First, the 'move' RPC command now generates AccountingEntry records with the current reference height rather than refheight=0. Second, the 'listaccounts' RPC command properly time-value adjusts AccountingEntry records.
