update Makefile tree, status.html, years.html, template/README.md.year

We add `make clang-format` to the Makefile tree.

Add `important disclaimers about contest status` link to `status.html`.

Update `years.html` due to recent commit that fixed typo for abstract of 2011/akari.

Improve `template/README.md.year` for future IOCCC contents.

Ran `make quick_www` to perform the above.
