[PATCH] status: allow branch info color customization

[Alexander 'z33ky' Hirsch <1zeeky@gmail.com>]

From: Alexander Hirsch <1zeeky@gmail.com>

git status -bs (--branch --short) does not seem to allow customization of the
colors for the local and remote branch.
This patch adds these via the color.status.local and color.status.remote
config variables.

Given the trivial nature of this patch I did not write a test for it. I did a
small check that it's working so, to be on the safe side.
