Added Android/Forms Windows scheme bindings

The Android designer & Forms previewer are plugins, but there's currently no way to define a scheme specific keyboard binding in a plugin. Thus the bindings are defined here. For the Visual Visual Windows binding scheme, these bindings match VS Windows (generally Control instead of Command). For the other schemes, the default bindings are used.
