bitbake: bitbake-diffsigs: colourise output

Browse Source 
If the output is a TTY, add colour to the output in order to make it
easier to read. At the moment this is fairly basic, just add colour to
the "titles" of each change and to the diff output.

I tried to introduce this without changing the code too much - rather
than moving everything over to the new python formatting style, I've
introduced a color_format() function which takes care of the colour
formatting, either accepting additional format arguments or
alternatively leaving the caller to use the old-style formatting (%) to
insert values.
