No way to use Standalone Month Name in QML

There's currently no way to use the StandaloneFormat [1] of longMonthName [2]. Qt object's only date functions - formatDate and formatDateTime [3] use QDate::toString() which assumes that DateFormat [1] should be used. In Polish language this results in it being impossible to format a date without day-of-month, like:

June 2010

which instead of

Czerwiec 2010

becomes

czerwca 2010

that can be compared to

of July 2010

in English

My proposal is to add an additional format "MMMMM" (5 Ms) that would use longMonthName with QDate::StandaloneFormat as the second argument, returning a singular, basic format of the month name.

I can provide a patch with that behavior if it's deemed an acceptable solution.
