a few small things

- document updates: traces, native, opcodes
- slightly better support for 65CE02 (handle Z register)
- more compatibility for 6502 processor: "jsr PRINT" and NMI/IRQ
- Instant Assembler now can use "jsr PRINT", no extra NMOS code needed
- again changes to historian
- historian now got a test script
- timcat now uses upper case
