[vos-d] templates/macros

[Peter Amstutz]

I went ahead and did it already, actually.  I needed the template functionality in the core so 
that I could specify VOS classes that are logically templates, such as UInt8DynamicArrayProperty 
(which is a property holding an array of bytes).  Without a template feature, I would have to do 
a lot of cut and paste to get DynamicStringArrayProperty, DynamicVector3ArrayProperty, etc...

The current scheme is somewhat incomplete though, we will need listeners to be able to properly 
propagate changes in the base template to all the template instances.
