Add documentation for usage on Linux through wine

[MaximumWoahverdrive]

The Windows build can be run on Linux through the popular compatibility layer wine, however some extra setup is necessary and should be documented where possible.
Below are the additional steps required for full functionality. (a general understanding of wine is assumed and usage of winetricks or a similar utility is recommended)

• Install corefonts
• Install dotnet 5 by running the windows installer
• Rendering problems and graphical glitches can be fixed by setting the following registry key HKCU\Software\Microsoft\Avalon.Graphics\DisableHWAcceleration to 1 of type REG_DWORD
• Buttons are missing proper icons if the Segoe MDL2 Assets font is missing.
  1. Put SegMDL2.ttf in [wineprefix]/drive_c/windows/Fonts SegoeFonts Download
  2. Set the registry key HKLM\Software\Microsoft\Windows NT\CurrentVersion\Fonts\Segoe MDL2 Assets of type REG_SZ (string) to SegMDL2.ttf
