buildhistory-diff: add support for colourising the output

Browse Source 
Colour value removes in red and additions in green, making it easier to scan the
output for relevant changes.

This adds a --colour option to specify whether colouring should be on, off, or
detected.  The default is detected, and depends on whether stdout is a TTY (same
behaviour as git).
