Add GlAppSwitchTest - switches between two Gl-using apps and forces recreating GlContext - replica island is used for one GL app. - if something goes wrong and rendering is blocked, watchdog timer in each app will fire - fixed a bug in GlPlanetsActivity as the original code freed vertex / index buffer and did not create after pause resume : Buffers are just kept to reduce resume time for this test
