Two major updates:

  * Added Android support (including VR devices like Oculus).
  * Automatized builds are complete. The way it works is by running `./nue game 
--platform:platformName` and it will autogen a plugin with your game targeting 
that particular platform. Notice the plugin will be per platform and only 
activated for that particular platform. The code will be compiled and 
statically linked by UBT just like it does for vanilla C++
