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)

9e5e21b8c9 Prevent uninitialized value bugs and improve string safety.
This change does two things:

1. Updates the registry APIs to reduce the likelihood of uninitialized
variables.

The code wasn't always checking the return value of registry load operations.
In some cases, this led to uninitialized memory being used, and crashes could
result. For example, LoadConfiguration in Applewin.cpp was using an
uninitialized value for the computer type if no registry variable for the
"Apple 2 type" was set.

New registry reading methods and macros have also been introduced, allowing
default value fallbacks for the cases where a registry variable is not found.
This makes registry access simpler and safer when a default value is known in
advance.

The registry code's style has also been updated to conform with the rest of
the code base (tabs instead of spaces, naming conventions, etc.)

2. Introduces string safety improvements.

A number of code paths have been modified to use safe-string functions instead
of their unsafe counterparts (e.g., strcpy, sprintf).  In the process, some
strings were converted from "char" to "TCHAR". This was done mostly for
consistency with the rest of the code-base.

Support vertical blending for 'RGB (Color Monitor)' for hires (#616) (PR #624)
Support the old AppleWin 1.25 vertical blending for hires:
- extended Config dialog to include 'Vertical Blend' checkbox
- Persist 'Video Styles' to Registry
- new cmd line options to select this style & also select 'RGB (Color Monitor)'
- code refactor to support enum VideoStyle_e (and replaced g_uHalfScanLines with a bit in g_eVideoStyles)

Bumped version to 1.28.2.0.

Support for AppleColor / Video7 DHGR mixed mode (#523) (PR #620)
Supported modes selected via toggling AN3 and clocking in 80COL:
- 140 color mode (Apple calls this mode 2, Video7 calls this mode 0).
- mixed mode (Apple calls this mode 3, Video7 calls this mode 2).
- 560 mono mode (Apple calls this mode 1, Video7 calls this mode 3).

Save-state is also persists the extra state.

And there's a few corrections to APPLE2E.SYM for the 80STORE and 80COL I/O addresses.

Reinstate support for old AppleWin 1.25 "Color (Standard)" video mode (#357) (PR #614)
Renamed this video mode to: "Color (RGB Monitor)"
Also renamed "Color (Monitor)" to "Color (NTSC Monitor)".

As for the colours: I've changed them from the original 1.25 colours. Instead I runtime-generate the colours from the NTSC code. See NTSC.cpp's GenerateBaseColors(). This shifts the same 4-bit pattern in, combining with NTSC color phase, until the colour stabilises. Then I average the next 4 RGB values to get the final colour. The reason for this is that we now have consistent colours between NTSC and this simplified rendering mode.

NB. The 2 greys (in GR,DGR,DHGR) are now the same RGB value.

Add support for PAL/European or custom 8K video ROMs (#596)
Added new cmd-line switch: -videorom <file> to replace the video ROM for the Enhanced //e.
- Support video ROM sizes of 4K, 8K and 16K (top 8K only).
- NB. The rocker switch is set to European video ROM.
F10 (for //e or Enhanced //e models) emulates the PAL //e's rocker switch (under the keyboard) to toggle between European or US video ROM.

Other:
- Fixed debugger's view of the AltCharSet soft-switch (it was showing the opposite state).

2d2304b4c6 AppleWin's Config>Benchmark, reported a "Pure CPU MHz" which was not a good indicator of unthrottled speed for v1.26+, as it was still getting the emulator to do full NTSC/cycle-accurate video update. The reality (when in full-speed/unthrottled mode) is that the video is only refreshed at 16.6ms (wall-clock).
So added a 2nd "Pure CPU MHz" for full-speed (ie. no video update), eg:

---------------------------
Benchmarks
---------------------------
Pure Video FPS:	2860 hires, 2868 text
Pure CPU MHz:	10.3 (video update)
Pure CPU MHz:	241.3 (full-speed)

EXPECTED AVERAGE VIDEO GAME
PERFORMANCE: 476 FPS
