rel-html: add 3.12 and 3.13 for projects

This updates all projects relying on following the
Linux kernel. Annotate which kernels are also EOL now
for the Linux kernel and remove completely unsupported
kernels. While at it, add 3.13 proactively, we may want
to just guestimate future releases but how do we do that?
