Added 16-bit INCs and DECs. Which don't set flags, so are easy.

Made an attempt to get the Z80 at least as far as rejecting an opcode.

Ensured initial program counter and stack pointer are correct for Zexall, fixed the Z80 to use a compile-time polymorphic call for bus access.

Factored out the stuff that both all-RAM processors would share, rather than duplicating it.

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.

Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.
