Update cocos2d_specifics.cpp

fix bug about scheduler, if this value is -1, it will work all right in Emulator, but run error in real device, just call one time.
Fix a memory leak in Set::removeAllObjects.
The set maintains a strong reference to all objects so release() should be called whenever something is removed from the set.

add EGL_RENDERABLE_TYPE to OpenGL attributes

This patch adds EGL_RENDERABLE_TYPE=EGL_OPENGL_ES2_BIT to the OpenGL attributes.
The default value for this setting is EGL_OPENGL_ES_BIT and, as we require ES 2.0,
cause some problems on various Android devices (e.g. Amazon Kindle 2.Gen).
wrong variable used which could crash the whole app
re-introduce Cocos2dxHelper.runOnGLThread(Runnable)

It's crucial to execute various tasks synchonized with the rendering loop /
thread, but this ability (runOnGLThread) got removed with the NativeActivity
transitions a few days ago. This patch adds this method back again.

Why can't we just use runOnUiThread()? Because it seems not to be synchronized
properly and can cause broken OpenGL textures or even the whole app to crash.

Isn't there a better way to get into the mainloop? I hope so! But I'm not a
experienced Android developer and this solution is quite simple / the only one
that worked without any problems.
