chistedit: add basic colours to diff view

This isn't complete, and it would be nice to show the exact same
colours that `hg diff` would show. That goal is too lofty, so this
just shows some basic colours, on the premise that a little is better
than nothing.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
