New: ValueDefinitionAttribute.FilterMenuGrouping is used to group items in the filter menu. For example, grouping on Article.Issue might be [IssueYear] desc or grouping on User.Region might be [CountryName], [StateName]. Note: the group column names must exist on the table of the column filtering by. For example, CountryName and StateName must also exist on the Users table.
New: ValueDefinitionAttribute.FilterMenuSortAscending is used to sort items in the filter menu. True = Ascending and False = Descending.
New: Add calculated property Article.IssueYear which is used to group issues in filter menu.
Fix: EnumerationDefinitionAttribute.DefaultValue produced an error when enumeration name like Now could be evaluated.
