Fix #360. 

This allows Region Sensor nodes to export
`plObjectInVolumeAndFacingDetector`, which only triggers the region
sensor when an avatar is in the region, facing a certain direction
(within a tolerance amount), and (optionally) moving forward.

BREAKING CHANGE: The Facing Target node can now only link to a single
condition node.
