    Attachment: QueryOverSqlFuncsExts.zip

Hi,
Regarding NH-2683, I've created an extension method (attached) which accepts a fluent based "SqlFunction().Restriction()" form methods as its argument. Please let me know what do you think about it.

> Some of the common functions (that are registered in most, if not all Dialects) can be used in ICriteria using SQL-projections.
> Extensions methods can be added for these to allow queries along the lines of:
> s.QueryOver<Person>()
>     .Where(p => p.BirthDate.Year() == 1970)
>     .List()
> ... which can be translated to:
>     .Where(Restrictions.Eq(Projections.SqlFunction("year", NHibernateUtil.DateTime, Projections.Property<Person>(p => p.BirthDate)), 1970))
> ... and in turn to:
>     datepart(year, this_.BirthDate) = @p0;
