Support Property Nodes on FPGA Targets

[Pie566942.0]

I would like to access class attributes of my FPGA class hierarchy with property nodes.  I prefer the property node API over VIs for data member access because it allows you to grab properties from across the hierarchy in a single node.  This leads to a (much) cleaner block diagram and expedites development.  For example in the screenshot below, the FXP attributes belong to the NI_9205 class, while the "_OP" attributes belong to the parent.  I don't care about the Invoke node API over a subVI, because the wiring work and diagram appearance are about the same IMHO.

Thanks,
