Use keys in dictionary if value for IN operator #301

This is the way the default NSSQLiteStoreType behaves. Iterating over an NSDictionary iterates over its keys as well.

Currently, if a dictionary is used as the value for IN in a predicate, it creates SQL: SELECT ... FROM ... WHERE (... IN ?); and produces the error could not prepare statement: near "?": syntax error.

With these changes, the SQL is: SELECT ... FROM ... WHERE (... IN (?, ?, ...));, where the bindings for ?, ?, ... are the dictionary's keys.
