[ABW]: curator_payout_value/total_payout_value now have '0.000 HBD' default to always have asset in value (ultimately they should be changed to numeric columns)
removed columns that we don't intend to update as they would hold irrelevant data: children_abs_rshares, reward_weight; also removed from queries
hive_posts_view no longer has parent_permlink - replaced with parent_permlink_or_category as that's what was in original comment data and what is expected
fixed order by time in list_comments_by_last_update, list_comments_by_author_last_update (newer first)
fixed payout update date - each operation that is part of payout has its own date as (at least some) can be from different blocks
fixed author_rewards - it is a sum of partial rewards for the comment
when payout operations are processed they no longer incorrectly overwrite each other's data
1969 year in date recognized as timestamp::max and replaced by infinity (and the other way when producing results) - fixes corner case of time ordering in by_cashout_time
commented out checks in run_tests.sh as they fail when address contains '-' like in 'hive-3.pl.syncad.com'
