Windows zip files need a better name and structure

[tclemos]

Current the windows release zip file contains a confusing structure.

We should get rid of the builds and windows folders.

Would be good to have something simpler and with a better name, like

flappy-gopher-windows.zip
│   flappy-gopher.exe
│   SDL2.dll
│   SDL2_image.dll
│   SDL2_ttf.dll
│
└───game
    ├───...
