Windows NT 5.x Notepad with fixes

Modified from the Windows NT 5.2 source, with additions from NotePadEx, and compiler optimizations.

• Use SSE2 SIMD instruction set extensions for both x86 and x64.
• Use the /O2 compiler flag for maximum optimizations.
• Change icon to classic NT one.
• Lint source and remove undefined variables.
• Fix building on MSVS 2017/2019.
• Add 'Ctrl+Shift+S' to open the "Save As" Dialog box.
• Enable "Word Wrap" and "Status Bar" to be enabled at the same time.
• Reduce flickering when resizing the Window on NT 6.0 and below.
• Name is changed to "Notepad NT" for most things.

Works on Windows XP - 10 (11 doesn't display it correctly)

– Add "Open New Window" option.

– Allow "Find" Dialog box to search backwards with 'Shift+F3'

Requires MSVS 2017 or 2019 and the v141_xp Windows XP toolchain.
This can be found in the Visual Studio Installer after going to "Individual Components" and searching for "Windows XP". Info Here.

The original source called for MSVS 2005, and the updated project files from vxiiduu called for MSVS 2010, but I wanted it to be able to build on modern Windows and modern MSVS, while still being able to build on Windows 7.

• Open the Notepad-NT.sln file and then you can build it.

Requires MSVS 2010 + Windows 7 SDK
This allows for Windows 2000 support.

• Open the Notepad-NT-msvs2010.sln file and then you can build it.
