removed .id files from winning dirs

The `.id` files are no longer needed and so they were removed.

The `winner_id` (the contents of the `.id` files) are simply
a concatenation of "year" and "_" and "dir".

Adjusted `.inventory.html`, `tmp/README.md`,
`tmp/fake.gen_inventory.sh`, and the manifest according
to the above.
