Uses the cursor now. Warning: Requires the cursor table to exist in the

Thresholds are now taken from columns in the txlist table. rmg_time can
optionally use a cursor table that stores positions that mark the last
point at which all previous data has been processed. Useful for starting
up quicker from crash recovery, etc. If the table isn't around, there's
functionality to locate unscored points by performing a left join
instead.
