Correct usage to track implementation

Split repository action into two parts; setting kerveros.ver variables goes in the middle, no longer conditioned on repository access.  This ensures that all substitution variables set correctly, even when the repository action is SKIP.

Avoid 'file not found' msg when deleting temp file.

BETA version not marked as RELEASE.

Create installer sandboxes from the staging area.  Build there and copy results back to staging area.  NSI build no longer picks up WIX build products.
