cogl-color: Provide setters for all the channels

Browse Source 
We only had getters for the red, green, blue and alpha channels of a
color. This meant that, if you wanted to change, say, the alpha
component of a color, one would need to query the red, green and blue
channels and use set_from_4ub() or set_from_4f().

Instead of this, just provide some setters for CoglColor, using the same
naming scheme than the existing getters.
