Continued edging towards getting the absolute basics of a testable Z80, for test-driven development. Corrected old-fashioned instance naming issues with the corresponding 6502 class and removed an unnecessary source file while at it.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.
