scripts/sjp: rewrite to Python
scripts/sjp: rewrite to Python

Reason - nokogiri was giving me headaches on Cygwin machine. Since I
don't care about Ruby much these days and I was too lazy to fix my
nokogiri installation (that would potentially probably break on future
machines), I decided it was a good to rewrite it to the language I
already use everywhere else.
