More work on block rewards in relation to account level/legacy qora held.

Rename Asset.QORA to Asset.QORT so we can also have Asset.LEGACY_QORA
as another hard-coded asset.

Add "is unspendable" aspect to assets where only the asset owner can
transfer/pay asset to other people. Asset trading is barred regardless,
as is use of asset for ATs.

Added "initial level" to account data in preparation for accounts levelling
up from generating blocks.

Added distribution/removal of block reward based on legacy-QORA held.

Removed "previous level" from ACCOUNT_LEVEL transactions as they're
only ever valid in genesis block and so previous level is never needed.
