improve register.html

We added lettered steps to `next/register.md` as part of our
configuring the mailing list for IOCCC28.

Change "IOCCC Judges" to the more commonly used "IOCCC judges"
and made it a HTML link in `2014/README.md`, `2015/README.md`,
and `faq.md`.

Added a reference to "first time login" in `next/submit.md`.

Improved some text in Step 3 of FAQ 0.0 of `faq.md`.

Performed `make quick_www` to update the HTML pages.

TODO: Need to add images to the lettered steps in `next/register.md.
