Static module scripting should update value of "valid?" output in "get index definition.vi"

[knoxberry]

If a static control module is created from a template without an channels initially, all channel classifications will be invalid after modification and scripting. This is common if a non-trivial control module with many channels is created.

This issue manifests itself when the editor node of the user control module is loaded into DCAF editor and the channels tab doesn't appear.

Fix - Scripting tool should change value of valid output depending on whether or not the user controls have data in the clusters. Maybe a better solution would be to use the "get supported channel classifications" as an override.
