* clutter/cogl/cogl-shader.h: Add a function for setting an
	integer uniform, similar to cogl_program_uniform_1f().

	* clutter/cogl/gl/cogl-program.c: Implement the GL version
	of cogl_program_uniform_1i().

	* clutter/cogl/gles/cogl-program.c: Implement the GLES version
	of cogl_program_uniform_1i().
