removed redundant "if ($state_index_id !== null) {"
* workaround: procurve & serverscheck
a sensor is causing create_state_index($state) to return null.
The updated code doesn't allow for this and thus a hybrid is being used.
* standardised naming of state info. Caused a typo $state_name instead of $status_name
$state_name is the standard
* converted compas to square arrays
* Converted APC states using preg_match to new create_state_index() call
* Update boss.inc.php
