PSUnreal Mac authorize app

Our PSUnreal Mac client is not signed. The reason is that to have it signed we need to pay a yearly fee to Apple, be part of the developers program, and get our app reviewed by them every time we do a release, which will slow down our releases and cost money.

So, for now we decided to avoid this and to keep it signed by us with a local certificate. For this reason you need to authorize the app and the developer (us) in your Mac, or you will not be able to run the game. This is done only once per app release.
