Automatically show the build version from Build Settings

I've found this, and has been proved really worth, all that I want is display a label on the menu on my games / apps, when you display the current version of your game, so you can debug things easily when you're trying to found / debug some bugs.

You will need to put this file, inside some Editor folder

What this will do is, as soon you open Unity, he will look for the Version from the Bundle Settings, and generate a new file for you, in this case one like these:
 

So whenever you want to display the current bundle version, just use simple as this:
 

And now you're ready to go :)

There is only a catch, this will be update when you open your unity, and ONLY when you open your Unity, so when you change the bundle version, you need to restart the unity so you get this new version.
