* Updated Alert->register to take a hash reference for message variables to simplify when a caller plans to log and register an alert at the same time.
* Updated Convert->bytes_to_human_readable() to name the 'size' variable used internally for 'bytes' to actually be 'bytes' for better consistency.
* Created multiple new Database methods;
** ->check_condition_age() is meant to be used by scan agents to see how long a given condition has been in play (ie: how long ago power was lost to a UPS or a sensor became unreadable).
** ->insert_or_update_health() handles recording data to the new 'health' table, used for determining ideal hosts for servers between nodes.
** ->insert_or_update_power() handles recording data to the new 'power' table, used for determining how power events are handled.
** ->insert_or_update_temperature() handles recording temperature data to the new 'temperature' table, used to determine how thermal events are handled.
* Got a lot more done on the scan-hardware scan agent. Only part left now is post-scan health processing.
