Add initial API Filter component

The purpose of this is to turn ZoneMinder filter queries into usable
CakePHP find() conditions.
As example would be turning
api/events/index/MonitorId:7/MonitorId:8/StartTime >=:2015-01-05.json
into an array like this:
'conditions' => array(
	'MonitorId' => (7, 8),
	'StartTime >=' => '2015-01-05'
)
