*Steps to reproduce:*
# Open attached project "My Project"
# Select asset "Select Me"
# Notice that the popup field shows an item and can be changed
# Open Script Editor/Example.cs
# comment out line 2
# Now select the asset and notice the value is None, the binding has failed.

*Actual results:* Object is not bound when using a type that is not Object

*Expected results:* Object is bound

*Reproducible with versions:* 6.000.2.0a11

*Not reproducible with versions:* 

*Can’t test with versions:* 

*Tested on (OS):* Windows

*Notes:*
* This is due to our binding code for Object references. The generic method used for Get and Set is hardcoded to Unity.Object 
* SerializedPropertyHelpers.GetObjectRefPropertyValue and SerializedPropertyHelpers.SetObjectRefPropertyValue

Can this be made generic or can SerializedObjectReferenceBinding work with fields other than ObjectField?
