Add nRefHeight to class CAccountingEntry, and add nBlockHeight parameter to GetAccountCreditDebit(). Fixes GH #42, but is backwards-incompatible with existing wallets.
Add "refheight" field to output of AcentryToJSON(). Fixes GH #48.
Change nRefHeight in version=2 transactions to be 32-bit instead of 64-bit. Fixes GH #56, but requires new genesis block.
Switched coinbase distribution to arithmetic progression, fixing GH #55. This will be a test for the second beta, with the option kept to revert before final release. A new genesis block still needs to be created.
Rebuilt genesis block using new transaction format (32-bit RefHeight instead of 64-bit), new initial block value, and new timestamp+nonce. Closes #58.
