Jorge Bernal 8c16f4c7d0 BGE: New Property sensor evaluation types
This patch adds "Less Than" and "Greater Than" evaluation types to the property sensor.
The Wiki Docs modifications http://wiki.blender.org/index.php/User:Lordloki/Doc:2.6/Manual/Game_Engine/Logic/Sensors/Property
Also, I have attached a screenshot and a blend to check.
