Add BDD AND_GIVEN based macros

issue #1360

It is possible to have multple  given contexts in a single BDD scenario;
if you have to type 'and' in the GIVEN description; it's very likely you
need an AND.

A generic AND  is not possible, thus a AND_GIVEN  is added to complement
the AND_WHEN and AND_THEN.

Can be used without needing to increase indent:

	SCENARIO("...") {
		GIVEN("...")
		AND_GIVEN("...") {
			WHEN("...") {
				THEN("...") {
					// ...
				}
			}
		}
	}

would correctly output, when requested/needed:

    Given: ...
And given: ...
     When: ...
     Then: ...

The padding had to be increased by a character in the output message, to
continue to be uniform.
