Jace 2012-10-31 build released: Trick or Treat?

[BLuRry <brendan.robert@gmail.com>]

] 65c02 CPU emulation is now 100%, tested and verified thanks to Klaus Dormann's test suite: https://github.com/redline6561/cl-6502/blob/b0087903428ec2a3794ba4219494005174d1b09f/tests/6502_functional_test.a65

] Overall CPU usage is way down thanks to recent changes:
    Video generation rolled into main thread and this made things a lot more efficient
    Switched to older timer model, newer lock-based timers were considerably slower
    Memory listener model streamlined to be more efficient

] Skyfox now detects mockingboard in slot 4
] Pitfall II detects mockingboard and plays perfectly!
] Disk II speedup hack now provided as a configuration option (previously, speedup hacks were always enabled to max the emulator speed when disk is in use)
] Hayes smartmodem now has UI activity indicators

Some folks reported in the past intermittent issues where the emulator would hang on start and never actually begin executing the rom (symptom: Screen with alternating checkerboard and inverse @ symbols).  I believe this release fixes that problem once and for all.

This is the most stable and efficient build to date, I hope it is useful to your folks!
