Add compatibility with Mac

Any chance of this getting mac osx support?

If you're reading this, then it's not yet implemented.
If you want this, then take these steps in order to get it working:
1. Install the plugin to your project
2. Modify `Restyle.uplugin` to support mac:
` "WhitelistPlatforms": [ "Win64", "Mac" ] `
3. Compile & Run
4. Reply what results you've got

Platform-specific notes:
CreateWidget node will remain old, because it spawns widget by itself (not by a node factory like everything else)
In order to make it spawn by factory, "function hooking" technique is used.
Without an ability to test, it's impossible to develop such tricky thing.

I don't own mac nor i can afford it. So there is no way to test it by myself.
