Title: Add Includes() and NotIncludes()

Added `assert.Len(t, someIterable, element)` which try to iterate over the iterable's elements to check if element is included on it.

It tries to iterate over an generic "list" like an slice, array... So I think it is an useful assert if you need to check if an "list" includes an specific element.
