issue #2770: fix some warning
issue #2771: add pointQuery
issue #2771: edit assert message
Fix a bug:we can use 'Custom Class' in CocosBuilder, and assign custom properties to it, but when you create some nodes with the same custom_class , and they have different custom properties, as they are same class and the share one Loader, so in the loader _customProperties will be wrong.
So, I dropped some lines to clear _customProperties before handle an new node.
