Made an attempt to introduce checking of bus activity against the FUSE tests. Appears to suggest 54 new failures.

Implemented inputs and outputs, determined how to answer port requests to please FUSE and hence reduced failures to 84.

Fixed Z80's ownership of its fetch-decode-execute program, its habit of scheduling invalidly when hitting an unrecognised operation and the test machine's habit of dereferencing invalidly.

Added a memory access delegate to the Z80 all-ram processor, to allow access patterns to be captured.

Fixed the 16-bit ADCs and SBCs, added INC (HL) and DEC (HL). Zexall now enters a seemingly-infinite loop. Which is progress, at least.

This logging has outlived its usefulness for now.

Added the concept of a trap handler to the all-RAM processor and exposed it via the test Z80 classes.

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

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.
