Support for synchronous events (PR #841)
Switched Mockingboard/6522 Timer interrupts & Mousecard's VBlank interrupt to use synchronous events.
This is a linked-list of ordered timer-based event, where only the head of the list needs updating after every opcode.

Support 2nd Disk][ card and improved card management (#726) (PR #741)
Support 2nd Disk][ in slot-5, via command line:
- -s5 diskii
- -s5d1 \<imagefile\>
- -s5d2 \<imagefile\>

NB. there's currently no Configuration UI support, except the Drive icons' tooltips show what's in slot-5 & slot-6 (for drive-n). So there's no way to eject the disks or insert new disks. The use-case I'm supporting it Wasteland which just has the 4 disks in the 4 drives.

Improved card management:
- Added `class Card` (in Card.h) which all other cards (that exist as classes) derive from (eg. LC,SSC,Mouse,Disk2).
- Added `class CardManager` (in CardManager.cpp\h) which now manages the 8 slots (and aux slot).
- Added `class Disk2CardManager` (in Disk2CardManager.cpp\h) which provides methods for operations that act on all Disk2 instances at the same time.
- Currently limited to just 1x SSC and 1x Mouse card (why would you need more?). This simplifies things, meaning there's no need to have dedicated SSCManager / MouseCardManager objects.
- Currently the 2nd Disk2 card can only be put into slot-5. This limitation is just due to the complexity of the Configuration UI. Having a more general drop-down per slot UI would remove this limitation.

Fix for "Mad Effect 1&2" demos (PR #725)
. 6502 interrupt delays 1 opcode when interrupt occurs on last cycle of opcode (#724).
. Only 1-cycle delay for VF_TEXT & VF_MIXED mode changes (#656).
NB. Mad Effect 1 still has a bit of flicker on Space Invader (left edge)

d4e01643fa Mockingboard: improved sound-buffer updating
. Changed to 6522.TIMER underflowing at 0x0000 -> 0xFFFF (#652)
. Changed MB_Update() to be based on cycle delta (was TIMER1 interval)
  . this improves support for small 6522.T1C interval
  . removed MB_GetFramePeriod()
  . removed overly-complex dual-timer support
. Replaced MB_EndOfVideoFrame() with MB_PeriodicUpdate()

498f01edde New save-state (.aws) v2:
Added card save/load for:
. Phasor (#260)
. CP/M (#260)
. 80 column card:
  . aux memory now saved separately from main memory
  . extended memory (RAMworks) (#260)

Mockingboard & Phasor:
. Full AY8910 internal state now preserved.
  . needed for eg. envelope, ay_change[], etc
  . also Phasor player only updates AY regs that have changed

Other:
. On restore error, then PostMessage(WM_USER_RESTART), so that emulator not left in intermediate state
. Fix: Start Dir wasn't set when drag & dropping an image onto a drive icon or double-clicking an image file
