Cleanup and slightly optimize the progress logging.
Previously the logging function which reports on progress was called for every block, regardless of whether it was an orphan or not. This could be confusing since it could show a different number of blocks processed as compared to the old versus new heights reported (orphans do not add to the block height since they aren't extending the main chain). Further, the database had to be consulted for the latest block since the block we just processed might not be the latest one if it was an orphan. This is quite a bit more time conusming than it should've been for progress reporting. This commit modifies that to only include non-orphan blocks. As a result, the latest height shown will match the number of blocks processed (even when there are orphans) and the additional block lookup from the database is avoided.
