[fedora-arm] Status Page

[Chris Tyler]

I've added a (rudimentary, really ugly) status page to the arm koji web
site. The URL is:

http://arm.koji.fedoraproject.org/status/

This page provides access to the log files from the current
build-previous and/or koji-shadow runs, and Paul Whalen added a link to
the last koji-compare run.

I hope to spruce this page up with some graphs, run stats, and other
information in the weeks ahead.
