Updates for dmd 2.066.
Some fix for debug.
Do not support Win9x.
DFL64: Fix application manifest

Change [processorArchitecture] value from X86 to N/A(= *).
This is an important fix of the application manifest, which is
referenced if a DFL application calls an initialization method,
Application#enableVisualStyles().
This does NOT make any change on Win32 programs.
DFL64: Update struct field sizes (ex. DWORD to DWORD_PTR)

Changed field types and sizes of Windows API structs into the
corresponding new type aliases such as DWORD_PTR, UINT_PTR, and so on.
This does NOT make any change on Win32 programs.
DFL64: Update CHOOSEFONT structs

Removed improper alignments from CHOOSEFONTW and CHOOSEFONTA, as defined
by Windows API.
While I do not see why these alignments need, at least, they are incorrect on Win64.
This does NOT any change on Win32 programs.
DFL64: Update common dialogs and common controls

Changed parameter types and return types of a few callbacks which are
defined in the Windows API.
The updated type aliases are such as DWORD_PTR, UINT_PTR, and so on.
The targets are ChooseColor, ChooseFont, and RichEdit.
This does NOT make any change on Win32 programs.
DFL64: Update window timer ID

Modified the type aliases of timer ID to UINT_PTR, which are used by API
functions.
This does NOT make any change on Win32 programs.
DFL64: SetWindowLongPtr/SetClassLongPtr

Replaced calls to Set/GetWindowLong() API functions with ones to
***LongPtr() functions which can handle 64bit values (ex. pointers and
resource handles).
Set/GetClassLong() are similer.
This does NOT make any change on Win32 programs.
FIX: Improper custom draw events handling

This fix is for a bug that DFL64 program crashes if using treeview
contains icon images.
To fix this, rewrite the whole event handling flow of NM_CUSTOMDRAW.
Note: Most important thing, the system allows only actions corresponding
to each Draw Stage.
