Canvas Batching System Dirties Project User-Created Materials when using Rect Mask 2D
Steps to reproduce:
1. Open user attached project
2. Enable the "Rect Mask 2D" component on the "Panel" Gameobject
3. Play the scene, then stop the scene
4. Click the menu "File" -> "Save Project"
5. Open the "CustomMaterial" asset in a text editor and notice that it now has "UNITY_UI_CLIP_RECT" as a shader keyword, it is a persistent project asset and now dirtied by the system. This would cause it to show up as a changed file on all source control systems, confusing developers and causing confusing merge conflicts.
6. Now, DISABLE the "Rect Mask 2D" component on the "Panel" Gameobject
7. Again play the scene, then stop the scene
8. Again click the menu "File" -> "Save Project"
9. Again open the "CustomMaterial" asset in a text editor and notice the "UNITY_UI_CLIP_RECT" shader keyword is now gone.
Expected result: canvas batching system should not dirty project user-created materials

This problem is causing extra work for us, always having to verify that material asset diffs are legitimate changes or random flip-flips of the ClipRect2D keyword. Please back-port this to 2017.4.X Please please pretty please. Thanks!

It appears this fix STILL hasn't hit the 2017.4 LTS branch. If you are targeting that release toward serious dev teams, this would be a good fix to port over there...
