Cache scrypt hashes on disk
instead of recalculating every time. This policy is able to give us 10-20x startng speed up. User can disable caching with -fastindex=0 option.

Note that this commit makes blockindex code incompatible with old blockchain database files. You need to remove old blockchain files and syncronize with the network again.

Another changes:

1. Stake pooled keys are removed.

Happy new year, guys and ladies!

P.S. Builds will be published tomorrow.

Some examples of usage.

• Key tree navigation (get a list of root nodes, move down from root to grand-grandchild);
• Node addition using a public and private derivation functions.

I suppose that deterministic keys generation feature will be ready for testing a few days later.

Some examples using incredibly experimental snapshot:

1. Creation of public & private key trees using seed (unlocked wallet emulation):

2. Creation of public keys tree using master public key and master chain code (locked wallet emulation):

Features planned for 0.4.4.6+

• Deterministic wallets, i.e. keychains generation from seed (user supplied or automatically generated, see Electrum for example);
• Separated databases for keys and transactions, instead of wallet.dat; (Questionable)
• Add support for free transactions and decrease the price for 1kb (i.e. bitcoin-like fees scheme);
• Remove lower output value limit for user and coinstake transaction types;
• Add maxtxfee configuration option and RPC call;
• Include PoW block txfees into the PoW block reward (like bitcoin does, to make transactions handling more profitable in comparison with empty PoW block generation). (Questionable)
