Virtual Data Warehouse v.1.6.3

Virtual Data Warehouse v.1.6.3. is effectively a bug-fix release that adds better exception handling in various places, especially when metadata (Json) files do not match the expected format.

This is now handled gracefully and warnings or errors are visible in the event log. Also, defaults are put in place to allow code generation for metadata that does confirm to the Data Warehouse Automation schema but is missing some details that VDW needs to build the user interface (e.g. mapping name, classification).

Lastly, a new feature was added to monitor the input directory (where the metadata files reside) on changes and update the user interface when metadata is modified, added or removed.
