Icon doesn't show

[beccabunny]

Using the lastest editor's nightly, Windows 10, the app's icon that was added by MZ in 1f154b0 doesn't appear, and instead only the default windows no-icon image is shown

I think this is a Windows-only issue. Pretty low on my priority list though. It's likely related to the lack of an "install" directive, which is where the icon stuff usually gets set up.

This was an issue with Endless Sky on Windows for a long time. See: endless-sky/endless-sky#926
