[PATCH 2/2] expand --pretty=format color options

From

Currently, the only colors available to --pretty=format users are red, green, and blue. Rather than expand it with a few new colors, this patch makes the usual config color syntax available, including more colors, backgrounds, and attributes.

Because colors are no longer bounded to a single word (e.g., %Cred), this uses a more advanced syntax that features a beginning and end delimiter (but the old syntax still works). So you can now do:

  git log --pretty=tformat:'%C(yellow)%h%C(reset) %s'
to emulate --pretty=oneline, or even
  git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)'
if you want to relive the awesomeness of 4-color CGA.

René: I saw you mention an end goal of implementing the other --pretty
formats in terms of --pretty=format:. So maybe this will help just a
little.
