inconsistent naming of variables in Alienability module

[nataliacp]

There are two variables involving Possessive Classification (HasPossessiveClassification and PossessiveClassificationType). This leads a user to believe that the PossessiveClassificationType variable is a further elaboration of the HasPossessiveClassification variable. However, the term Possessive Classification is not referring to the same thing in the two variables. HasPossessiveClassification is derived automatically from two other variables (HasBoundNouns and/or PossessiveClassesCount different than zero). But Possessive Classification in PossessiveClassificationType includes languages (all with the state semantic) that have no possessive classes at all and no bound nouns. (Samoan, Chamorro, Warao, Maori, Greenlanding Eskimo).
