The final fix of noun phrases with cardinal numbers in Russian

The support for variation of the noun depending on what cardinal it is
used with seems to be complete by now ("one child - two children -
five children" - Russian has different plural forms for "a child" when
counting). The case agreement in noun phrases that have additional
determiners besides numerals ("three little blind mice") is fixed too.
