Up max fps value to 65 on Android targets

On weak targets, like OUYA, setting FPS at 65 compared to capping it at 60 (if we are still in the need of capping such a value) max helps a lot: a program set at 60fps will almost never hit the 60fps average and go for 55-57fps, whereas setting it at 65 will ensure hitting 60fps. One can enable.disable as well vsync to make sure everything is ok.
