Increments your Unity Build version number, every build or manually via MenuItem button.

Version 1.1 Credits:
JamesDev for original script inspiration
&& JesusLuvsYooh StephenAllenGames.co.uk for auto build feature and editing.
&& Nick for beating me to a fix

This file must be in an "Editor" folder (Unity/Assets/Editor) for example.
Set autoIncreamentBuildVersion to false, to disable auto version changing.
This script should increase the end number of your version;
So..
0 would become 1
1.1 would become 1.2
1.2.3 would become 1.2.4

Console output for build, displaying before and after incremented version number.


Result of build with incremented version number.


Optional Menu Item, for manually increasing build version.

Enjoy! ^_^
