Updata To Unity 2019.1.4f1

[YichSouls]

Hello gjrgj,

I'm a user of your tools for a long time for about 3 months. Really appreciate what you have accomplished and this tool really save a lot of time for debugging for MagicLeap. As the SDK of MagicLeap would no longer support on the Unity 2018, I have to change your script for manually type the path of certificat and SDK to work. I expect you can update your tools for Unity 2019 or otherwise maybe allow me to contribute to the project? Waiting for your response.

Best regard
