Standard Assets bundle has various issues.

I'm trying to use water from the standard assets but many problems.

* There is some code GUIText that is resulting in a compilation error. This has to be changed to Text and UnityEngine.UI needs to be referenced.

* Theres a rolling error..

* The water is visible in Game View (Edit mode) but when run the water isn't visible, though the ground beneath it is greyed out.
