Support DELETE FROM statements

[miyconst]

It is very often required to execute DELETE FROM SQL statement, although it's possible to use typeof and nameof operators without major performance hit, it still would be nice to support those statements with LINQ.

Something like:

// Delete all objects from Person table.
Objects<Person>.Delete();

// Delete objects from Person table if Name equals to test.
Objects<Person>.Delete(x => x.Name == "test");

Does Delete method support the same filtering predicates as Where does?

Yes. I added additional tests for this feature.
