Subject: [PATCH] account_exists needs to be transactional Adding
 ledger::forked_block as a utility function to retrieve the block with which
 block_a conflicts in the local ledger.  Since this could be either an
 open_block fork or normal fork, which have different semantics. Testing to
 make sure a forked open_block will bootstrap correctly. Initializing
 QApplication before it's required which isn't alway supported.
