[Android] Due to recent changes in code breaking Tegra 4 support, and also the upcoming code which will be breaking GLES2 support entirely. Taking the initiative to drop the remaining support code from the codebase in preparation for the upcoming changes. For a look at how Dolphin on Tegra 4 looked like prior and would not have been able to be fixed at all due to Tegra 4 not supporting the precision we need in our shaders; Look at this Youtube video http://youtu.be/Ga7Jc_Ote7U
