fix typo for baseUrl when configuring configuration.txt

use osmosis --read-replication-lag to determine if there are changes before trying to process updates, useful when we are tracking hourly or daily replication updates

set CONST_Replication_Recheck_Interval to 60

skip lag check if CONST_Replication_Update_Interval > 60, for minutelies there's always new diffs to process

use tabs for indent

change sleep for non-minutely updates so that we dont drift tto much or poll excessively

unset $aReplicationLag before each exec attempt

unset $aReplicationLag inside while loop
