Bring README and TODO.md in line with the tree on next2 (closes #111)

The README layout lists src/library/ and the other source files, the
backup layout names failures.json and the optional thumbnails/, "Opening
a library" says an empty cache opens with no data when the first refresh
fails, and the Testing section gives the 60-second hard cap and 20-second
target for make test, with the 90-second timeout in the Dockerfile's test
phase as the backstop that catches a hung test. The next step in both
files is storing live photos
(#107) instead of a v1.0.0 tag;
tagging and releases are sneak's call alone.
