Add mpv folder to start menu folder

[shinchiro]

To mimic standard installation on windows. I found it can be useful. A folder can have:

• mpv shortcut
• open cmd in current folder
• mpv-uninstall.bat shortcut
• manual.pdf shortcut
• etc..

start menu folder located in %AppData%\Microsoft\Windows\Start Menu\Programs

Agreed, though it's not easy to make a shortcut from a batch file with out-of-the-box Windows tools. (Maybe PowerShell could do it?)
