Title: Do not throw on unrecognized locale + update plural rules.

While working on HTML Localization, I noticied that plural-rules module was too strict.
So intead of throwing an exception and breaking everything, I've updated the code to just print a warning message.

In parallel, unicode.org website has updated Hebrew (`he`) plural rule.
That's why there is so many modifications, the rule #2 is new and specific to `he` locale.
All next rules are unmodified, their index just bumped by one.
