patch to add genitive month names support using %Om to pl_PL locale
Slavic languages, like Polish, use different cases for month names when they are on their own (nominative, "styczeń") and when they are part of a date (genitive, "11 stycznia"). Currently Polish locale only have nominative forms, so calendars use ungrammatical forms.
Attached patch to pl_PL locale adds a solution similar to the one found in uk_UA locale:
It uses alt_digits to present a list of month names in proper form for dates.
I suggest closing this bug report as a duplicate of bug 10871 because:
* the other bug, although originally referring to Russian only, provides a large list of affected languages, see bug 10871 comment 6;
* Piotr has already admitted that both his patch and an existing solution for Ukrainian which inspired him are "hacks, dirty workarounds really" - see https://bugzilla.gnome.org/show_bug.cgi?id=749206#c3.
I'm really excited and looking forward to your work. :)
