Add Description Field to FPGA I/O Properties.

[WNM]

The "FPGA I/O Properties" that can be set for an I/O point under an FPGA target consist of just the name for the I/O point.

On the other hand, the "Shared Variable Properties" that can be set for a similar I/O point under a cRIO chassis are much more extensive and include a description field.

I'd like to see a similar description field included/available for the FPGA I/O points. As it is information that is maintained as part of the "project", the reduced functionality normally associated with an FPGA should not be an issue.

As long as I'm wishing, it would also be nice to be able to export/import names/descriptions/properties from something akin to the "Multiple Variable Editor" for both "FPGA I/O Properties" and "Shared Variable Properties" and if an I/O module is moved from the FPGA level to the cRIO level or vice versa, allow us to transfer or import the relevant properties from one level to the other.
