TTP# 337136 - SETTINGS: Target Platform settings polish
TTP# 337652 - EDITOR: Limit Project supported Android icons down to 1
TTP# 337650 - EDITOR: There is only 1 icon for Apple for Project Supported Platforms
DesktopPlatform now contains a static array of FPlatformInfo. This can be used to query UE4 about its available platforms, even when they're not available as a target platform.
FPlatformInfo contains the information required by the editor (such as a localized display name and icon), as well as whether a platform is a variation ("flavor") of another, and if so, whether the flavor affects the build output (eg, Win32 or Win64), or the cook output (eg, Android_XYZ). This lets the editor build up nested menus for the "Package Project" and "Cook Project" options, rather than just showing everything as a flat list.

TTP# 332489 - TOOLS FEATURE: Editor: Allow user to designate which platforms a project is designed for; warn user when deploying to platforms that will result in a bad time
There is now a "Target Platforms" tab in the project settings which allows you to choose which platforms your project will target. This information is stored inside the .uproject file.
If you try and launch, cook, or package for a project that isn't on the supported list, then you'll see a suppressible warning notifying you that the project may not run as expected. This is also conveyed to you via a warning icon next to platforms which aren't set as a target.
Additionally the target platform icons are shown in the tooltip on the "Open Project" dialog, as well as in the tab area of the level editor.
