[PING][BZ 10871] Month names in genitive case

[Rafal Luzynski]

Hi,

Sorry for this delay. I have fulfilled all legal requirements so you
can review my set of patches without worrying about the copyright issues.

The aim is to allow the month names to be formatted correctly using
two grammatical cases depending on the context as required by the rules
of several languages (including my native).
