TextureSequence Shader Support; GLMediaPlayer uses 'int' where possible; General enhancments.

For details about TextureSequence/GLMediaPlayer shader collaboration w/ your own shader source,
see TextureSequence and TexCubeES2 / MovieSimple demo.

TextureSequence allows implementations to provide their own texture lookup function
which may provide color space conversion (YUV) .. or other runtime hw-accel features.
Have a look at the next commit, which provides an Libav/FFMpeg implementation w/ YUV/RGB shader conversion.

MovieCube adds keyboard control (Android: firm touch on display to launch keyboard, don't break it though :)
