Title: Basic configuration validation for overlays

Added some python glue for overlays so they will check to see if they are associated with properly existing renders. If not, error out.

Still need to have the code in JS that uses this Information. I figure these are some semi harmless set of changes so they can probably be committed before figuring out the JS.
