This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke <jeffrey@ethereum.org>
